concurring' in part and dissenting in part

This is an interlocutory appeal from the trial court’s order denying the defendant-physicians’ motions to dismiss under the Medical Liability and Insurance Improvement Act (“MLIIA”) for failure of the plaintiffs to file an expert report meeting the requirements of Texas Civil Practice and Remedies Code sections 74.351 and 74.401 with respect to their acts of medical negligence.

Although the majority has recited the correct standard of review, it has ignored that standard in conducting its analysis. It subjects the three expert reports to a rigorous de novo review rather than the review for abuse of discretion called for by the Civil Practice and Remedies Code, and it construes the statutory requirements for medical malpractice expert reports and the judicial requirements for proving the reliability of experts so strictly as to assure the dismissal with prejudice of many meritorious claims at the expert report stage-that is, prior to discovery — rather than to deter the bringing of frivolous claims, as intended by the expert report requirement.

Returning this case to the trial court so that the plaintiff may attempt to surmount the virtually insurmountable hurdles the majority has created for establishing the reliability of expert reports creates the very real possibility of dismissal with prejudice of all claims against the cardiologist whose act of alleged negligence in severing the patient’s artery during emergency placement of a stent initiated the chain of negligent acts that together directly and proximately caused the death of the patient from prolonged lack of oxygen to the brain. And this is so even though, under a reasonable reading of controlling law, all three expert reports fully satisfy the requirements of the Texas Civil Practice and *715Remedies Code, and all three expert witnesses are reliable.

The majority concomitantly fails to appreciate or adequately address the situation in which, as here, more than one physician’s negligence was a proximate cause of a patient’s harm. It thus ignores the fact — repeatedly referenced in each of the three medical reports — that the death of the patient, Donald Wendt, from lack of oxygen to the brain following an emergency catheterization procedure was proximately caused by both the initial rupturing of the left anterior descending coronary artery (“LAD”) by the emergency cath lab cardiologist, Dr. Earl Mangin, during placement of the stent and the failure of the cardiologist to get the heart pumping again as blood pooled up in a tamponade in the pericardial sac so that Wendt’s heart could not pump blood to his brain. And the majority likewise ignores the significance of the fact that each expert opined that it was the delay in getting oxygen to Wendt’s brain for well over an hour in the cath lab while CPR was performed that was the cause of Wendt’s death — not any one specific act of any one person.

The trial court found the' three expert reports adequate as to both Dr. Mangin, the cardiologist who placed the emergency stent in Wendt’s heart and ruptured his LAD, and Dr. Zbigniew Wojciechowski, the attending anesthesiologist in the emergency cath lab. The majority holds that two of the three expert reports — those of anesthesiologists Dr. Abdul Q. Memon and Dr. Willliam J. Mazzei — are sufficient to allow the case to proceed against Dr. Wo-jciechowski for his acts and omissions in treating Wendt at Sugar Land Methodist Hospital on January 9, 2012, two days after his admission for chest pains. The majority, therefore, affirms the trial court’s denial of Dr. Wojciechowski’s motion to dismiss.

However, the majority also concludes that the expert report of Dr. Paul W. Dlabal, a practicing cardiologist, is not an objective good faith effort to comply with the statute as to Dr. Mangin, also a cardiologist. And it concludes that the expert report of anesthesiologist Dr, Mazzei is, likewise, not an objective good faith effort to comply with the requirements for an expert report as to Dr. Mangin. It then finds that the expert report of Dr. Memon, an anesthesiologist certified as an “advanced Cardiac Life Support Provider,” is deficient as to Dr. Mangin on several grounds, but principally, in its view, for failing to establish Dr. Memon’s credentials to opine on the standard of care of a cardiologist. It, therefore, reverses the trial court’s order denying Dr. Mangin’s motion to dismiss and remands the case against Dr. Mangin with instructions to the court to afford the Wendts an opportunity to cure, if possible, the deficiency in Dr. Memon’s report within thirty days.

I cannot conclude on these facts and the substance of these three expert reports— when there are multiple acts of negligence specifically attributable to more than one defendant that together proximately caused the harm on which a-medical liability suit is based — that either of the two defendants, Dr. Mangin or Dr. Wojcie-chowski, is .entitled to dismissal of the claims against him with prejudice in advance of discovery and without a trial on the merits on the ground that the expert reports did not contain enough information to satisfy the appellate court — not the trial court — as to the specific act by that physician that by itself directly caused the harm on which the suit is based. Finding all of the reports adequate, either individually or when read together, as expressly permitted by both the plain language of Civil Practice and Remedies Code section 74.351(i) and by controlling authority, I would affirm the trial court’s denial of both doctors’ motions to dismiss.

*716I believe the majority has, in its analysis of this:case, elevated'the'Standard of appellate review of medical expert' reports far above the standard abuse of discretion by the trial court established by the Texas Supreme Court, and its. opinion repeatedly contradicts that standard. I also believe that the majority opinion contradicts corn-trolling Texas Supreme Court precedent and puts 'this Court on a conflict course with our sister ‘'intermediate appellate courts — and even with' past decisions of this Court — that will inevitably lead to arbitrary and inconsistent opinions regarding the adequacy of'medical expert reports, with great harm to the law.

The issues in this case are especially important because, under the MLIIA, expert reports are a statutory threshold requirement for maintenance of a suit for medical negligence against a physician. Therefore, dismissal of a claim for failure to satisfy the standards Of section 74.351 is with prejudice and entitles the.defendant to attorney’s-fees.- Thus, if the appellate courts are 'falling into disagreement as; to what those standards require, it is important that the supreme court clarify what is required to satisfy the threshold requirement of 'statutorily sufficient expert reports — especially in cases with multiple defendants, each of whom committed an act of negligence that was a proximate cause of harm to the patient — to show that the plaintiffs case is meritorious so that thé case can proceed to discovery and trial on the merits. It is equally important that the supreme court further ‘clarify' the 'abuse of discretion standard of appellate review of medical expert reports.

Medical Expert Reports under Civil Practice and Remedies Code Chapter 74

A. Civil Practice and Remedies Code Sections 74.351 and 74.401

. The Civil Practice and Remedies Code provides:

In a health care, .liability, claim, a claimant shall, not later than the 120th day after each defendant’s original answer is filed, serve on that party or the party’s attorney one or- more expert reports, with a.curriculum vitae of each expert listed in the report for each physician or health care; provider against whom a liability claim: is asserted. The .date for serving the report.may-be extended by written agreement of the’ affected parties. Each defendant physician • or health care provider whose conduct is implicated in a report must file and serve any objection to the sufficiency of the report not later than the. later of the 21st day after the.date the report is .served or the 21st.day after the date the defendant’s answer is filed, failing which all objections-- are, waived.

Tex. Civ. Prac. & Rem. Code Ann. § 74.351(a) (Vernon Supp. 2014). If the Claimant fails to serve the physician with an expert report, the trial court shall enter ah order dismissing the claim “with prejudice to the refiling of the claim” and awarding reasonable attorney’s fees and costs. Id. § 74.351(b). However,

If an expert report has' not been served within the period specified by Subsection (a) because elements of the report are found deficient, the court may grant one 30-day extension to the claimant in order to curé the deficiency. If the claimant does not receive notice of the court’s ruling granting the extension until after the 120-day deadline has passed,' then the 30-day extension shall run from the date the plaintiff first received the notice.

Id. § 74.351(c).

Regarding the qualifications of an expert witness in a suit against a physician, *717the Civil Practice and Remedies Code provides:

(a) In a suiti involving a health care liability claim against a physician for injury to or death of a patient, a person may qualify as .an expert witness on the issue of whether the physician departed from accepted standards of medical care only.if the person is a physician who:

(1) is practicing medicine at the time such testimony is given or was practicing medicine, at the time the -claim arose;

(2) has knowledge of accepted standards of medical care-for the diagno-. sis, care, or treatment of the illness, injury, or < condition involved in the claim; and

(3) is qualified on the basis of training or experience to offer an expert opinion regarding those accepted standards of medical care.

[[Image here]]

(c) In determining whether a witness is qualified on the basis of training or experience, the court shall consider whether, at the time .the claim arose or at the time the testimony is given, the witness:.

(1) is board certified or has other substantial training or experience in an area of medical practice relevant -to the claim; and

(2) is actively practicing medicine in rendering medical care services relevant to the claim.

(d) The court shall apply the criteria specified in Subsections (a),- (b), and (c) in determining whether an expert is qualified to offer expert testimony on the issue of whether the physician departed from accepted standards of medical care, but may depart from those criteria if, under the circumstances, the court determines that there is a good reason to admit the expert’s testimony.. The court shall state on the record the reason for admitting the testimony if the court departs from the criteria.

Id. § 74.401 (Vernon 2011).

B. Standard of Review

The majority generally recites the correct standard.of review of medical malpractice claims as stated by the Texas Supreme Court. The standard is elaborated below, to clarify how the statute is to be construed by the appellate courts under controlling law.

“Plaintiffs suing on health care liability claims must serve each defendant with an expert report ... or face dismissal of-their claims.” TTHR Ltd. P’ship v. Moreno, 401 S.W.3d 41, 42 (Tex. 2013); see Tex. Civ. Prac. & Rem. Code Ann. § 74.351 (service of expert report required). “A valid expert report under the [Chapter 74] must provide: (1) a fair summary of the applicable standards of care; (2) the manner in which the physician or health care provider failed to meet those standards; and (3) the-causal relationship between that failure and the harm alleged.” TTHR Ltd. P’ship, 401 S.W.3d at 44 (citing Tex. Civ. Prac. & Rem. Code Ann. § 74.351(r)(6)). “A causal relationship is established by proof that the negligent act or omission constituted a substantial factor in bringing about the harm and absent, the act or omission, the harm would not have occurred.” Cornejo v. Hilgers, 446 S.W.3d 113, 123 (Tex.App.-Houston [1st Dist.] 2014, pet. denied). “[I]t is sufficient, that, in their reports, the experts ‘state[ ] a chain of events that begin- with a health care provider’s negligence and end in personal injury.’ ” Id. at 126 (quoting McKellar v. Cervantes, 367 S.W.3d 478, 485 (Tex.App.-Texarkana 2012, no pet.)).

“The expert report need not marshal every bit of the plaintiffs evidence,” Jernigan v. Langley, 195 S.W.3d 91, 93 (Tex. 2006), but it must “explain, to a reasonable *718degree, how and why the breach caused the injury based on the facts presented.” Jelinek v. Casas, 328 S.W.3d 526, 539-40 (Tex. 2010). "While a ‘fair summary’ is something less than a full statement of the applicable standard of care and how it was breached, even a fair summary must set out what care was expected, but not given.” Am. Transitional Care Ctrs. of Tex., Inc. v. Palacios, 46 S.W.3d 873, 880 (Tex. 2001). “It is not sufficient for an expert to simply state that he or she knows the standard of care and concludes it was [or was not] met.” Id. A medical expert report must provide enough information to fulfill two purposes: (1) it must inform the defendant of the specific conduct the plaintiff has called into question; and (2) it must provide a basis for the trial court to conclude that the claims have merit. Scoresby v. Santittan, 346 S.W.3d 546, 556 (Tex. 2011); Cornejo, 446 S.W.3d at 120. “No particular words or formality are required, but bare conclusions will not suffice.” Scoresby, 346 S.W.3d at 556; Cornejo, 446 S.W.3d at 123.

A report that merely states an expert’s conclusions is insufficient. Bowie Mem’l Hosp. v. Wright, 79 S.W.3d 48, 52 (Tex. 2002). Instead, the expert must provide a basis for his statements and must connect his ultimate conclusions to the facts presented in a particular case. Id. A plaintiff may file more than one report to fully satisfy the statutory report requirements. See Tex. Civ. Prac. & Rem. Code Ann. § 74.351(i); see also Cornejo, 446 S.W.3d at 120 (“The expert report requirement may be satisfied by utilizing more than one expert report, and the court may read the reports together.”).

When a defendant challenges the adequacy of an expert report, the trial court may grant a motion to dismiss “only if it appears to the court, after hearing, that the report does not represent an objective good faith effort to comply” with the statutory definition of an expert report. Tex. Civ. Prac. & Rem. Code Ann. § 74.351(7). A report qualifies as an objective good faith effort to comply if it meets the two purposes of an expert report in that it (1) informs the defendant of the specific conduct the plaintiff questions, and (2) provides a basis for the trial court to conclude that the plaintiffs claims have merit. Loaisiga v. Cerda, 379 S.W.3d 248, 260 (Tex. 2012) (citing Scoresby, 346 S.W.3d at 556, and Palacios, 46 S.W.3d at 879). In determining whether an expert report is an objective good faith effort to comply, a court may look only at the document itself “because all the information relevant to the inquiry is contained within [its] four corners.” Wright, 79 S.W.3d at 52.

If the court finds the report to be deficient — but nevertheless an objective good faith effort to comply — then it may grant the plaintiff one thirty-day extension to cure the deficiency. See Tex. Civ. Prac. & Rem. Code Ann. § 74.351(c); Scoresby, 346 S.W.3d at 557 (“We conclude that a thirty-day extension to cure deficiencies in an expert report may be granted if the report is served by the statutory deadline, if it contains the opinion of an individual with expertise that the claim has merit, and if the defendant’s conduct is implicated.”). However, if it appears after a hearing that the report does not represent a good-faith effort to comply with the definition of an expert report or is not sufficiently specific for the trial court to conclude that the claims have merit, the court must dismiss the claims against that defendant. See Cornejo, 446 S.W.3d at 120.

Dismissal of a claim against a physician or health care provider for failure to file a timely report meeting the requirements of section 74.351 is with prejudice to refiling the claim against that physician or health care provider and entitles the defendant to *719attorney’s fees. Tex. Civ. Prac. & Rem. Code Ann. § 74.351(a), (b); see Obstetrical & Gynecological Assocs., P.A. v. McCoy, 283 S.W.3d 96, 101 (Tex.App.-Houston [14th Dist.] 2009, pet. denied) (holding that if plaintiff does not timely serve adequate expert report as to particular defendant in health care liability claim, trial court has no discretion to do anything other than dismiss case with prejudice).

We review a trial court’s ruling on a motion to dismiss pursuant to section 74.351 for abuse of discretion. Palacios, 46 S.W.3d at 878; Cornejo, 446 S.W.3d at 119. A trial court abuses its discretion if it acts in an arbitrary or unreasonable manner without reference to any guiding rules or principles. Jelinek, 328 S.W.3d at 539 (emphasis added); Walker v. Gutierrez, 111 S.W.3d 56, 62 (Tex. 2003); Cornejo, 446 S.W.3d at 119. When reviewing matters committed to the trial court’s discretion, the appellate court may not substitute its own judgment for that of the trial court. Wright, 79 S.W.3d at 52; Walker v. Packer, 827 S.W.2d 833, 839 (Tex. 1992); Cornejo, 446 S.W.3d at 119. An appellate court may not reverse for abuse of discretion simply because it would have decided the matter differently. Downer v. Aquamarine Operators, Inc., 701 S.W.2d 238, 242 (Tex. 1985); Cornejo, 446 S.W.3d at 119.

Moreover, when a party can show that an expert is substantially developed in more than one field testimony can come from the qualified expert in any of those fields. Broders v. Heise, 924 S.W.2d 148, 154 (Tex. 1996). The- offering party must show that the expert has the “knowledge, skill, experience, training or education regarding the specific issue before the court which would qualify the expert to give an opinion on the particular subject.” Id. (internal quotations omitted). Absent a clear abuse of discretion, the supreme court will not disturb a trial court’s ruling on the qualifications of an witness as an expert. Id. at 151.

Adequacy of Expert Reports of Drs. Mazzei, Dlabal, and Memon

Dr. Mangin was the cardiologist who perforated the artery of the deceased, Donald Wendt, while performing an angioplasty and implanting a stent. Dr. Wojcie-chowski was the anesthesiologist on duty in the emergency catheterization lab when Wendt was taken there, and he “prepared and signed the anesthesia report indicating he was present during the procedure.” It remains unclear which part of Wendt’s care Dr. Wojciechowski provided, however, because a medical record also indicates that “Dr. Smith” — -who appears to be Dr. Stetch — was also “an anesthesiologist during the relevant periods” Wendt spent in the emergency cath lab.

In three issues, Dr. Mangin argues that the reports were inadequate as to him because (1) an anesthesiologist — which two of the experts are — is not qualified to opine on the standard of care for an inter-ventional cardiologist, (2) the reports did not state the applicable standard of care or the manner in which he allegedly breached it, and (3) the reports failed to explain how a breach of the standard of care caused the Wendts’ injuries.

In one issue, Dr. Wojciechowski argues that the trial court erred by denying his motion to dismiss because the reports are so deficient as to constitute no report as to him.

I would hold that all of the expert reports read singly and together satisfy the requirements of sections 74.351 and 74.401 as to both defendants.

A. Expert Report of Dr, Mazzei

The majority cursorily dismisses the expert report of -anesthesiologist Dr. Mazzei *720with respect to Dr. Mangin. The majority opines that “Dr. Mazzei’s report made no assertions and drew no conclusions relevant to Dr. Mangin or to any cardiologist generally” and - thus “standing alone this report did not satisfy any of the three statutory expert report requirements as to Dr. Mangin.” Op. at 706. It concludes the report was adequate as to Dr. Wojciechowski. Id. at 24-25.

To provide an adequate expert medical report, Dr. Mazzei was required to provide “(1) a fair summary of the applicable standards of care; (2) the manner in which the physicianfe] or health care provider[s] failed to meet those standards; and (3) the causal relationship' between that- failure and the harm alleged,” here, Wendt’s death from cardiac arrest following his admission to Sugar Land Methodist Hospital. See TTHR Ltd. P’ship, 401 S.W.3d at 44 (citing Tex. Civ. Prac. & Rem. Code Ann. § 74.351(r)(6)).

Dr. Mazzei opined that he was a physician licensed to practice medicine in California, who had completed “fellowships in vascular anesthesia, thoracic anesthesia, and critical care at the Massachusetts General Hospital in Boston, Massachusetts,” that he had been board certified in anesthesiology since April 1987, had practiced at the University of California San Diego School of Medicine since February 1986, was, at the time of the report, “Clinical Professor and Vice Chairman of the Department of Anesthesiology,” and “frequently provide[d] anesthesia for adults undergoing cardiac catheterization procedures and [was] thoroughly familiar with ventilation problems that may arise in the course of an emergency.” As such, he was “familiar with the standard of care that applies to the Institutions and health care providers in Texas.” He thus showed that he was fully qualified to testify as to the standards of care of both institutions and health care providers in Texas with respect to ventilation problems in the handling of an emergency cardiac catheterization.

Dr. Mazzei stated that he had reviewed Wendt’s medical records, and he set out the history of his treatment: Wendt entered the emergency room complaining of chest pain and was diagnosed with “acute myocardial infarction.” He was “brought emergently to the cardiac catheterization lab where stenoses of the mid and- distal LAD [coronary arteries] were found. These were angioplastied and a stent was placed, but the distal LAD was tom and blood began accumulating in the pericardium.” Dr. Mazzei recounted the various unsuccessful attempts to establish an airway for Wendt, the use of CPR to attempt to restart his heart, and the eventual surgical intervention that repaired the damage caused to Wendt’s artery during placement of the stent and to his liver during CPR.

Dr. Mazzei stated, “Although the' surgery was successful, Mr. Wendt had suffered massive anoxic brain damage and expired two days later.” He then opined:

When a patient requires emergency airway management as Mr. Wendt did, the standard of care requires that the anesthesiologist quickly assess the patient’s condition, perform an evaluation of the airway, and bring the necessary and potentially needed equipment and drugs to ventilate and intubate the patient. Of primary importance is to assure, regardless of drugs or methods chosen, that the patient remain adequately ventilated. Because of the tear in Mr. Wendt’s coronary artery that was thus bleeding into his pericardium, it. was reasonable to assume that he could lose consciousness at any moment and then lose the ability to protect and maintain his airway, as well as lose the ability to *721breathe. Thus, the standard ¡of care required that Mr. Wendt be- [placed under anesthesia and] immediately intubat-ed.

Dr. Mazzei stated that Wendt was properly placed under anesthesia, “but the anesthesia provider was'unable to intubate using standard laryngoscopy” or by other methods and Wendt’s oxygen saturation levels dropped to critical levels.. The low saturation levels weakened his heart, which caused cardiac arrest. Dr. Mazzei stated,

Although the blood leaking into the pericardium made it more difficult for Mr. Wendt’s heart to pump, it was the low saturations that caused..his heart to arrest. The low saturations were caused by inadequate ventilation. Although the anesthesia provider attempted to ventilate Mr. Wendt, he/she took too much time to re-establish adequate ventilation. This was below the standard of care and led to Mr. Wendt’s anoxic brain damage and subsequent demise.

He then summarized:

Mr. Donald Wendt was a previously healthy 57-year-old white male who suffered an acute myocardial infarction. While undergoing coronary re-vasculari-zation in the cardiac cath lab, his LAD was tom and blood started accumulating around his heart. ' This prompted the need for emergency airway management, for which an anesthesia provider responded. This provider induced anesthesia which stopped Mr. Wendt from breathing on his own, but then failed to re-establish sufficient ventilation before a cardiac arrest occurred. This failure was below the standard of care, and was the proximate cause of the cardiac arrest that led to anoxic brain damage and ultimate demise.

Dr. Mazzei’s expert report clearly satisfies the thrée expert requirements as-'to the anesthesiologist, Dr. Wojciechowski, who signed the anesthesiology report, by providing (1) a fair summary of the applicable standards of care; (2) the manner in which the physician or health care providers to Donald Wendt failed to meet those standards; and (3).the causal relationship between that failure and the harm alleged. All of these requirements are explicitly referenced and satisfied in Dr. Mazzei’s report. As the majority reaches the same conclusion, I concur with- , the majority opinion as -to Dr, Mazzei’s report with respect to Dr. Wojciechowski.

With respect to Dr. Mangin, the report recites Dr. Mazzei’s qualifications with respect to testifying as to ventilation problems in the handling of an 'emergency cardiac catheterization. It then states, “Because of the tear in Mr. Wendt’s coronary artery that was thus bleeding into his pericardium, it was reasonable to assume that he could lose consciousness at any moment and then lose the ability to protect and maintain his airway, as well as lose the ability to breathe. Thus, the standard of care required that Mr. Wendt be [placed under anesthesia and] immediately- intubated.” While the report states that he was properly placed under anesthesia, it also states, “Although the blood leaking into the pericardium made it more difficult for Mr. Wendt’s heart to pump, it was the low saturations that caused his heart to arrest. The low satu-rations were caused by inadequate ventilation.” Finally, the report states, “While undergoing coronary re-vascularization in the cardiac cath lab, [Mr. Wendt’s] LAD was tom and blood started accumulating around his heart. This prompted the need for emergency airway management.”

I read these statements as expressly implicating Dr. Mangin’s act of tearing Wendt’s artery during placement of the stent and allowing blood to -accumulate *722around the heart, impeding its ability to pump oxygen to the brain, as being acts below the standard of care that, together with the anesthesiologist’s inability to intu-bate Wendt, and the long delay in getting Wendt to .surgery where he could be intu-bated and his artery repaired, constituted a proximate cause of the loss of oxygen to the brain that caused Wendt’s death. See Cornejo, 446 S.W.3d at 123 (“[I]t is sufficient that, in their reports, the experts ‘state[ ] a chain of events that begin with a health care provider’s negligence and end in personal injury,’ ’’); McKellar, 367 S.W.3d at 486 (holding same). And the trial court abuses its discretion only when it acts in an arbitrary or unreasonable manner without reference to any guiding rules or principles. Jelinek, 328 S.W.3d at 539; Walker, 111 S.W.3d at 62. I cannot say that the trial court abused its discretion under these standards in. finding Dr. Mazzei’s report to be adequate as to both Dr. Mangin and Dr. Wojciechowski.

B. Expert Report of Dr. Dlabal

I likewise do not agree with the majority’s conclusory two-paragraph dismissal with respect to Dr. Mangin of the report of Dr. Dlabal — like Dr. Mangin- a practicing cardiologist and the only expert cardiologist to opine in thé case — as not an objective good faith effort to comply with the statute. Nor do I agree with the majority’s failure even to mention Dr. Dlabal’s report with respect to Dr. Wojciechowski.

In one paragraph, the majority dismisses Dr. Dlabal’s report as made in bad faith with respect to Dr. Mangin. It characterizes the report by saying only, '

Dr. Dlabal’s report reviewed and summarized the medical records from the two days Mr. Wendt was in the hospital before his death. He opined that the cause of death was loss of oxygen to the brain, a consequence of complications of treatment for a heart attack — in particular the perforation of a coronary artery. -As to causation, he-wrote: “The primary cause of death was cerebral anoxia. Had coronary perforation and its attendant complications not occurred in the course of treatment, the underlying condition was, in reasonable medical probability, survivable.”

Op. at 707. On the basis of this characterization, the majority concludes:

This report fails to satisfy the statutory requirements because it did not identify any applicable standards of care, assert that Dr. Mangin failed to Comply with’ an applicable standard of care, or explain how a departure from an applicable standard of care caused Mr. Wendt’s death. See [Tex. Civ. Prac. & Rem. Code § 74.351(r)(6)]. Because' Dr. Dlabal’s report merely summarized the medical records, it did not inform Dr. Mangin of the conduct that the plaintiffs had questioned nor did it provide a basis for the trial court to conclude the claims have merit. See Palacios, 46 S.W.3d at 879.

Id. I do not agree with this characterization of the report or with the majority’s conclusion.

Despite the .majority’s contention, Dr. Dlabal not only summarized Mr. Wendt’s medical records, he also opined that the cause of death was loss of. oxygen to the brain (cerebral anoxia), which was a. consequence of complications of treatment for a survivable heart attack, “in particular the perforation of a-coronary artery.” He described in detail how the negligent actions of both the attending cardiologist and the attending anesthesiologist — neither of whom he identified by name-r-caused Wendt to lose oxygen to the brain for a prolonged period of time.

As stated in his report, Dr. Dlabal is “board certified .in Internal Medicine and Cardiovascular Diseases, and [has] been in *723the active practice of cardiology since 1980.” He incorporated his curriculum vitae by reference. He further stated:

In my practice as a cardiologist, I have evaluated and treated numerous patients who presented with the symptoms and signs as exhibited by Donald Wendt on 2/7/12. In particular, I have evaluated and treated over 2500 patients who presented in an emergent condition suggestive of acute myocardial infarction, including numerous patients with acute anterior and anterolateral myocardial infarction. I am intimately familiar with the evaluation, treatment, and prognosis for patients presenting symptoms and signs as shown in the records for this patient.

He stated that his opinion was based on information in the medical records he had reviewed but was “not limited thereto and is subject to change should additional findings be brought'to bear on this matter.”

Dr. Dlabal recited thé history of Wendt’s treatment in the emergency and operating room. He stated that Wendt presented at the Sugar Land Methodist Hospital with chest pain of less than two hours’ duration. The initial examination showed hypertension and tachycardia, and he “was taken emergency to the catheteri-zation laboratory where he was found to have high-grade stenosis at the level of the mid and distal left anterior descending (LAD) coronary artery.” A stent was placed in the LAD lesion, but the distal LAD was perforated during the procedure, “with intrapericardial bleeding” caused by the perforation, which caused “pericardial tamponade.” This is a life-threatening situation in which the heart is so filled with fluid that -it cannot expand and pump oxygen to the brain. It was also an act of malpractice that was the first step in causing Wendt’s death, without which, in Dr. Dlabal’s opinion based on “reasonable medical probability,” he would not have died. At this time, -Dr. Mangin was in charge of Wendt.

A cardiovascular surgeon and anesthesiologist were called; Dr. Dlabal devotes a paragraph to the fumbling around of the anesthesiologist, “[djuring [which] time the patient progressively deteriorated into hy-potension and cardiac arrest for which CPR was initiated,” with oxygen saturation dropping to 70%, and, “[i]n all, CPR continued for nearly 60 fninutes.”

Dr. Dlabal’s report states that, after that, the patient was taken to the operating room, a laceration in the liver caused by the CPR was repaired, and “[a]n in-traaortic balloon pump ... was placed for circulatory support,” but “[mjultiple postoperative complications were noted including atrial fibrillation, respiratory failure, abnormal liver function test, and anoxic brain injury secondary to hypoxemia [abnormally low oxygen in the blood] and prolonged shock.” The patient showed “anoxic encephalopathy,” or brain damage due to cardiac arrest, “and did not regain consciousness.”

On the basis of those facts, Dr. Dlabal gavé his “Medical Opinion Regarding Causation”:

As a consequence of intraoperative complications of coronary perforation, hy-poxemia associated with hypotension, cardiac tamponade and circulatory collapse requiring prolonged CPR, the patient suffered irreparable brain damage on the basis of cerebral anoxia. Despite cardiovascular recovery from myocardial infarction, cardiogenic shock and cardiac arrest, the patient’s brain did not recover function, nor did he regain consciousness. The primary cause of death was cerebral anoxia. Had coronary perforation and its attendant complications not occurred in the course of treatment, *724the underlying condition was, in reaonable medical probability, swrvivable.

Report of Dr. Dlabal (emphasis added).

As with Dr. Mazzei’s report, I, unlike the majority, cannot conclude that the trial court abused its discretion by finding Dr. Dlabal’s expert, report adequate. See Palacios, 46 S.W.3d at 878; Cornejo, 446 S.W.3d at 119; see also Jelinek, 328 S.W.3d at 539 (trial court abuses its discretion if it acts by arbitrary or unreasonable manner without reference to any guiding rules or principles); Wright, 79 S.W.3d at 52 (“When reviewing matters committed to the trial court’s discretion, the appellate court may not substitute its own judgment for that of the trial court.”).

Dr. Dlabal, on the basis of a great deal of experience in treating “over 2500 patients who presented in an' emergent condition suggestive of acute myocardial infarction,” effectively reports that Dir. Mangin, the cardiologist who placed the stent, fell below the standard of care of a cardiologist by perforating Wendt’s artery, causing blood to fill the sac around the heart and compress the heart so that it could not expand, causing “hypoxemia associated with hypotension,” or- loss' of oxygen to the brain. I do not find it necessary that the expert report explicitly say that this, is below the standard of. care of a cardiologist in charge of a patient in an emergency cardiac cath lab in whose heart he has just placed a stent, because his expert report leaves room for no other conclusion than that the initial proximate cause of Wendt’s need to have ventilation restored to his brain was the perforation of his LAD by Dr. Mangin that caused blood to fill the pericardial sac so that Wendt’s heart could not compres? and pump oxygenated blood to the brain.

Dr. Mangin was in charge of the patient’s care from the moment the patient entered the emergency room for placement of the stent. He caused the initial injury by tearing Wendt’s artery, causing blood to pool up around the heart so that it could not pump oxygen to the brain. This situation occasioned the need for emergency repair of the ruptured artery and for oxygenation to keep the patient alive until that situation could be corrected, as Dr. Dlabal’s report states. Dr. Dlabal’s report makes it obvious that Dr. Mangin failed to carry out-this responsibility.

Section 74.351(r) requires only that a medical expert’s report provide “a fair summary of the expert’s opinions ... regarding applicable standards of- care,” identify "the manner in which the care rendered by the physician or health care provider failed to meet the standards,” and contain an explanation of the “causal relationship between that failure and the injury, harm, or damages claimed.’’ Tex. Civ. Prac. & Rem. Code Ann. § 74.351(r)(6). Dr. Dlabal stated, “Had coronary perforation and ifs attendant complications - not occurred in. the course of treatment, the underlying condition was, in reasonable medical probability, survivable.” Thus, Dr. Dlabal’s opinion necessitates the conclusion that the perforation of Wendt’s artery — done by Dr. Mangin — was the initial cause of all the complications that followed and was therefore a proximate cause of his death.

Likewise, Dr. Dlabal clearly sets out, in much greater detail than I have here, the many missteps committed by the anesthesiologist in getting oxygen to Wendt’s brain onee his heart ceased to be able to pump the blood — missteps that included “esophageal intubation,” instead of intubation of the lungs to bring air to them, causing- a need for “bag valve-mask ventilation and ultimately ... tracheal intubation.” During all this time, Wendt’s blood oxygen level was falling -into the' danger zone and his condition “progressively dete*725riorated into hypotension and cardiac arrest for which CPR was initiated,” and CPR was continued for. nearly an hour-before Wendt was taken to the operating room where the coronary perforation was repaired. Thus, the surgical repair happened so late that Wendt suffered “a trial fibrillation, respiratory failure, abnormal liver function test, and anoxic brain injury secondary to hypoxemia and' prolonged shock,” resulting in death.

I call this a clear statement of acts below the professional standard of care of both the cardiologist and the anesthesiologist charged with Wendt’s care that directly caused Wendt’s death. But the majority, in its review of the expert report, refuses-to translate'the medical language used or to draw any reasonable inferences from the physician’s statement; Most importantly, it fails to take into account the basic premise of law that an injury may have more than one proximate cause, as proximate cause is nothing but cause in fact plus foreseeability. See W. Invs., Inc. v. Urena, 162 S.W.3d 547, 551 (Tex. 2005) (“Proximate cause has two elements: cause in fact and foreseeability,” both of which must be established by evidence; “The test for cause in fact is whether the act or omission was a substantial factor in causing the injury without which the harm would not have occurred.”); Aleman v. Ben E. Keith Co., 227 S.W.3d 304, 310 (Tex.App.-Houston [1st Dist.] 2007, no pet.) (“Foreseeability exists, if the actor,as a person of ordinary intelligence, should have anticipated the dangers his negligent act creates for others.”). In the medicalreport context specifically, “[a] causal relationship is established by proof that the negligent act or omission constituted a substantial factor in bringing about the harm and absent the act or omission, the harm would not have occurred.” Cornejo, 446 S.W.3d at 123. And it fails to follow the established standard for appellate review of a trial court’s ruling on the sufficiency of a medical expert-report: Did -the trial court, act without reference to any guiding- rules or principles in determining that the report was sufficient. See Jelinek, 328 S.W.3d at 529.

In summary, the majority refuses to recognize that an injury in a medical malpractice case may have more than one cause— that it may result from more than one negligent act, with both being substantial factors in causing the harm in that the harm would not have occurred without both acts of negligence. Yet this court has specifically recognized that possibility in previous cases. See Cornejo, 446 S.W.3d at 123 (“[I]t is sufficient that, in their reports, the experts ‘state[] a chain of events that begin with a health care provider’s negligence and end in personal injury.’ ”) (quoting McKellar, 367 S.W.3d at 485).

In iny view, nothing more is' required to satisfy all the requirements of section 74.351(r) than that the expert report show the three elements of negligence — duty, breach, and proximate causation of injury — are satisfied. I cannot agree that construction of the statute requires a reviewing court to disregard reasonable inferences from expert statements that establish the duty or standard of care, the failure tó ’ meet that standard, and the causal relationship between the breach and the injury. And I cannot .agree that, in finding Dr. Dlabal’s report to be sufficient, the trial court acted arbitrarily and capriciously and without reference to any guiding rulés or principles.

Thus, I do not agree with the majority that the trial court abused its' discretion by accepting Dr. Dlabal’s report as adequate as to Dr; Mangin. To me, it is a necessary inference from the facts and opinions stated in Dr. Dlabal’s report that it is below *726the professional standard of care of a cardiologist to perforate an artery, causing blood to accumulate in the pericardium and the heart to be unable to beat to aerate the blood, which was a life-threatening situation that caused Wendt’s heart to stop beating and was allowed to persist for at least an "hour before surgical intervention repaired the defect. It is likewise below the standard of professional care for an anesthesiologist to intubate a patient’s' esophagus instead of his lungs, to take so long to intubate the patient that his blood oxygen level causes brain damage, and then for medical personnel to try CPR for an hour in the presence of both the cardiologist and the anesthesiologist before taking the patient into surgery to repair the tear and restore circulation of oxygen to his brain. Dr. Dlabal’s report supports the conclusion that all of these acts constituted departures from the professional standard of care of a physician; and each of them was a proximate cause of the “injury, harm, or damages claimed” — brain damage and death due to low oxygen caused by the unprofessional injury to Wendt’s coronary artery, the maladroit in-tubation, and the great lapse of time before taking Wendt to the operating room and performing, the necessary procedures to restore oxygen to his brain.

I note that, in stating the standard of care, breach, and causation, “[n]o particular words or formality are required,” and Dr. Dlabal’s report offers much more than “bare conclusions.” See Scoresby, 346 S.W.3d at 556; Cornejo, 446 S.W.3d at 123. However, even if section 74.351 required Dr. Dlabal to explicitly opine that the standard of care does not permit these failures and that they are below the standard of care of a reasonably prudent physician performing the tasks Dr. Mangin and Dr. Wojciechowski did perform (whether individually or in a supervisory capacity, or whether by simply standing by without taking the necessary steps to restore aeration to Wendt’s blood before he suffered irreversible' brain damage due to loss of oxygen is unclear), I could not opine, as the majority does, that Dr. Dlabal’s expert report is not an objective good faith effort to comply with the statute. See Op. at 706-07.

C. Expert Report of Dr. Memon

Lastly, the majority considers the report of Dr. Memon, who like Dr. Mazzei is an anesthesiologist. As with .the other reports, the majority applies far too stringent a standard of review to Dr. Memon’s qualifications to opine on Dr. Mangin’s treatment of Wendt, in my view. , It also finds the report deficient as to Dr. Mangin, although adequate as to Dr. Wojciechow-ski. I would find it adequate as to both.

The majority acknowledges that, “[t]o determine whether a witness is qualified based on his training and experience,” a trial court must consider whether the witness is “board certified or has other substantial training or experience in an area of medical practice relevant to the claim” and whether he “is actively practicing medicine in rendering medical care services relevant to the claim.” Op. at 707 (quoting Tex. Civ. Prac. & Rem. Code Ann. § 74.401(c)).

It further acknowledges that “[t]he critical inquiry is ‘whether the expert’s expertise goes to the very matter on which he or she is to give an opinion.” Id. at 707 (quoting Broders, 924 S.W.2d at 153). Thus a physician may be qualified to provide an expert report even when his specialty differs from that of the defendant “if he has practical knowledge of what is usually and customarily done by other practitioners under circumstances similar to those confronting the malpractice defendant,” or if “the subject matter is common to and equally recognized and developed in *727all fields of practice.” Id.; accord Keo v. Vu, 76 S.W.3d 725, 732 (Tex.App.-Houston [1st Dist.] 2002, pet. denied). For example, courts of appeals have held that experts whose specialty differed from that of the defendant were qualified when the alleged breach involved: a home health care worker’s failure to recognize and act upon signs of a true medical emergency, IPH Health Care Servs., Inc. v. Ramsey, No. 01-12-00390-CV, 2013 WL 1183307, at *10 (Tex.App.-Houston [1st Dist.] Mar. 21, 2013, no pet.) (mem.op.); general surgical practices such as preoperative and postoperative counseling and care, Keo, 76 S.W.3d at 733; post-operative infection, Garza v. Keillor, 623 S.W.2d 669, 671 (Tex.Civ.App.-Houston [1st Dist.] 1981, writ ref'd n.r.e.); and taking a medical history and giving discharge instructions, Hersh v. Hendley, 626 S.W.2d 151, 155 (Tex.App.-Fort Worth 1981, no writ).

However, the majority fails entirely to take into account the rest of Broders ’ instruction. In that ease, the supreme court held that when a party can show that an expert is substantially developed in more than one field, testimony can come from the expert in any of those fields. Broders, 924 S.W.2d at 153-54. The offering party is required to show that the expert has the “ ‘knowledge, skill, experience, training or education’ regarding the specific issue before the court which would qualify the expert to give an opinion on the particular subject,” but he is not required to do more; and, absent a clear abuse of discretion, the supreme court will- not disturb a trial court’s decision on the qualifications of a witness as an expert. Id. There was no such clear abuse of discretion here.

Dr. Memon’s expert report states, among other things, that he is a physician licensed to practice in five states, received his Texas medical license in 1977, has been certified by the American Board of Anesthesiology since 2000, is a fellow of the American College of Anesthesiology, is certified by the American Heart Association as an Advanced Cardiac Life Support Provider, has been certified by the American Heart Association as a Healthcare Provider, and is familiar With the standard care that applies to physicians and institutions in Texas. It further states,

As a practicing anesthesiologist, I am experienced in the preoperative evaluation, airway management, including placement of an Endotracheal tube (“ETube”), and administration of anesthesia to patients undergoing surgical procedures, including cardiac procedures. Further, I am familiar with the possible complications that can arise during treatment of an acute myocardial infarction and • the remedial measures necessary if such complications arise.

The report further states:

I also am familiar with and have substantial knowledge of the causal relationship between an anesthesiologist’s and general and traumatic surgeon’s failures to meet the reasonable, prudent, and accepted standards of medical care and supervision in the diagnosis, care, and treatment of patients requiring ventilation and/or undergoing general anesthesia for cardiac surgical procedures under both planned and emergent conditions.

The report states that Dr. Memon’s opinions were based upon, but were not limited to, Wendt’s medical records at Sugar Land Methodist Hospital on February 7 to February 9, 2012 and that “[t]he opinions expressed herein as to causation are based on reasonable medical probability.”

Dr; Memon opined with respect to Dr. Mangin:

In my opinion, the accepted Texas standards of medical care applicable under similar circumstances involved in air*728way management, necessitated by the complication of a ruptured artery during cardiac procedures and subsequently including emergent placement of an ETtube, requires that the patient’s condition be quickly, assessed, necessary equipment and drugs be made available immediately, a viable airway be established promptly and adequate ventilation be maintained during the course of any procedures. The cardiologist’s report clearly states that the ETtube was incorrectly placed. . No one record shows how long the tube remained incorrectly .place in the esophagus. The records do not show that anyone confirmed that the ETtube was in the correct place by either listening at the chest, a standard procedure in such cases. Finally, the records do not show how long it took to correct any mistakes and resume adequate ventilation after the initial failure, to properly intubate the patient. The records do show, however, that Donald Wendt was without a sufficient Oxygen saturation for significant periods of time during the cardiac incidents, had blood oxygen levels at a level low enough to cause organ damage for a prolonged period of time, pñor to being brought to the surgical OR.

An esophageal intubation is not an uncommon complication for an anesthesiologist, but a failure to promptly notice the incorrect placement and/or the failure to perform tests verifying correct placement and promptly correct the ET-tube placement or otherwise ventilate the patient, and not establishing a viable airway quickly is - a departure from the standard of care. Dr. Mangin’s record states that the anesthesiologist incorrectly placed the- ETtube in the esophagus, citing air in the stomach, and does not mention how long it took Dr. Smith1 to monitor and correct the placement.

As an anesthesiologist, I am familiar with the need to establish both a viable airway and sufficient blood flow to maintain necessary oxygen levels in the body and prevent organ damage during cardiac procedures. In my opinion, the accepted standards of medical care applicable to Dr. Mangin under similar circumstances involving the treatment of a patient with an acute myocardial infarction (“MI”), but who is ‘ alert and ambulatory, generally requires transfer of the patient to the cath lab for an ang-iography and stent insertion. However, the standard of care requires that the doctor who administers the sedation holds hospital privileges to do so. Further, while not very common, a ruptured artery and cardiac tampdnade are known complications of a stent insertion, and the doctor performing the procedure should be prepared to promptly deal with such complication by,' for example, draining a tamponade *729to re-establish proper circulation to essential systems.

In the ease of Donald Wendt, the records show that, despite conscious sedation administered at the cath lab, the patient’s pain and agitation increased significantly after the initial attempt to place a stent, resulting in a decision to call an anesthesiologist for general anesthesia and intubation. However, the records show that Dopamine was administered to. the patient, a sign that Donald Wendt was in cardiac distress and low blood pressure, well before any calls for specialists were made. Specialists such as an anesthesiologist or a cardiac surgeon should be called as soon as any problem is apparent. In the case of Donald Wendt, Dopamine was administered at 3:45 am according to the records, showing hypotension, pri- or to any call for either the anesthesiologist, at 8:49 am, or the cardiac surgeon at 4:10 am. The cardiac surgeon did not arrive until 1:22 am, significantly after Donald Wendt’s heart had stopped and CPB had been performed, and at which time the patient’s blood oxygen levels had reached a low enough level to result in organ damage. As pericardio-centesis was not performed until after the cardiac surgeon had arrived, it leaves open the question of ivhether Dr. Mangin knew how to drain a tampo-nade? And, if he was not qualified to address this possible complication, ivhy did Dr. Mangin choose to do a procedure with that risk? Further,' Donald Wendt’s medical records do not show when Dr. Mangin noticed the ruptured coronary artery; a failure-to promptly notice the rupture and take steps to prevent further damages is a deviation from the standard of care. From the records, it can be seen that the cardiac surgeon’ was not called for by Dr, Man-gin until 25 minutes after cardiac com-

plications set in. The cardiac surgeon’s arrival at the cath lab, after the delay in being called and. the time needed to arrive, was a considerable time after the initial complications became > obvious (as can be determined, by . the administration of emergency drugs, such as Dopamine discussed above), at which time it is medically likely that an acute tam-ponade had occurred, preventing sufficient blood flow to vital organs, including the brain.

A ruptured coronary artery and cardiac tamponade are not common complications, however, there is a significant chance of adequate' survival if aggressive treatment is immediately offered. If Dr. Mangin timely recognized the arterial rupture, and had he promptly per;formed a pericardiocentesis, a procedure performed by emergency medical professionals and cardiologists certified in the procedure as'well as by cardiac surgeons, and maintained blood flow to Donald Wendt’s brain and other organs, given adequate ventilation, it is my opinion, to a reasonable degree of medical probability, that he would not have suffered the period of hypoxia that left him brain dead.

In summary, Donald Wendt came to [Sugar Land-Methodist Hospital] walking alert and quite healthy for his age except for chest pain and left the hospital dead two days later, having never regained consciousness. In my opinion, the patient was brain damaged by the prolonged hypoxia and prolonged low Oxygen saturation that could happen when Donald Wendt suffered esophageal intubation, cardiac tamponade and ruptured coronary artery, which are - serious complication of a cardiac procedure. Any or all of these complications must be addressed promptly to avoid prolonged hypoxia, brain damage, and *730death, but if recognized and remedied quickly there is a reasonable certainty that the patient will have adequate recovery. During the procedures in the cath lab, Donald Wendt was hypoxic for a long enough time to become significantly brain damaged and unable to recover.

(Emphasis added.)

In my view, the majority opinion does not accurately reflect either Dr. Memon’s credentials or the content of his report. Consequently, it finds deficiencies where none exist on an objectively reasonable reading of the report. The majority states, “In his report, Dr. Memon stated that the applicable standards of care required Dr. Mangin to be prepared to ‘promptly deal with’ a ruptured artery and cardiac tamponade, both of which are known complications of a stent insertion, and to call for specialists such as an anesthesiologist or cardiac surgeon ‘as soon as any problem is apparent.”’ Op. at 708. The majority then opines, “With respect to the first of these proposed standards of care, Dr. Memon’s report raised a question about whether Dr. Mangin knew how to drain a tamponade, but he did not actually offer an opinion that Dr. Mangin was unqualified to perform a stent insertion.” Id. at 708. Rather, the majority construes the report as suggesting that “Dr. Mangin may have erred by choosing to perform a risky procedure if he was unqualified to perform it.” Id. With respect to the second of these proposed standards of care, the majority summarizes Dr. Memon’s observations about the administration of Dopamine to Wendt at 3:45 am and noted his characterization of that treatment “as ‘a sign’ that Mr. Wendt ‘was in cardiac distress’ and had Tow blood pressure.’ ” Id. The majority states, “Dr. Memon’s report opined that if Dr. Mangin had promptly noticed the ruptured artery, performed pericardiocentesis, and maintained blood flow to the brain, Mr. Wendt ‘would not have suffered the period of hypoxia that left-him brain dead.’ ” Id. at 708.

The majority, in finding this report deficient, picks bits and pieces of Dr. Memon’s opinion out of the fact-intensive context in which they are found and raises them to the sine qua non of an adequate expert report. Among other problems, the majority ignores the several aspects of the standards of care of a cardiologist charged with the emergent care of a cardiac patient that Dr. Memon did actually assign to Dr. Mangin — which, along with the breaches of these standards, are italicized in the report as set out above. And it misconstrues the import of what Dr. Memon did include in his opinion. The question regarding whether Dr. Mangin knew how to drain a tamponade is not raised because Dr. Mem-on is opining that he knows how to drain a tamponade and Dr. Mangin does not. It is raised as one possible reason for the tam-ponade’s being allowed to increase over a prolonged pei'iod of time to the point where Wendt’s heart stopped and he had no supply of oxygen to the brain for a long time before Dr. Mangin called someone capable of dealing with the problems he was experiencing with the patient.

It is not necessary for the report to set out the exact reason for each of the delays that Dr. Memon repeatedly says fell below the standard of care of both the cardiologist in the room — Dr. Mangin — and the anesthesiologist in the room — Dr. Wojcie-chowski — and that together proximately caused the lack of oxygen to the brain that caused Wendt, an otherwise healthy 57-year-old, to suffer organ failure and death. Those issues are to be discovered and presented at trial. All that is required for the adequacy of the expert report is for a qualified expert to have set out the stan*731dard of care, the facts constituting breach and causation, and the injury or damage caused by the breach. Those criteria were satisfied here.

The majority, however, having questioned Dr. Memon’s knowledge of how to drain a tamponade, next claims that he lacked the credentials to opine on the standard of care for a cardiologist called on an emergency basis to place a stent in the heart of a man with a blockage in the left anterior descending artery. The majority states, “We must determine whether Dr. Memon’s report and CV demonstrate that he is qualified to offer specific expert opinions considering that he is neither board certified in nor actively practicing cardiology.” Op. at 708 (citing Tex. Civ. Prac. & Rem. Code Ann. § 74.401(c)).

After reciting Dr. Memon’s credentials, it opines,

Although he asserts familiarity with standards of care for “general and traumatic surgeons,” Dr. Memon does not make any assertions of expertise pertaining to a cardiologist’s duties when providing cardiac care. The report also does not explain whether and how Dr. Memon’s knowledge about the standards applicable to “general and traumatic surgeons” applied to the specific breaches that he attributes" to Dr. Mángin. Moreover, Dr. Memon’s statement‘that he is “familiar” with the complications that can arise during treatment for acute myocardial infarction and the treatments for such complications is vague and nonspecific. In sum, the expert report does not demonstrate how Dr. Memon’s knowledge, skill, experience, training, or education qualified him to render an opinion about the particular breaches of the standard of care applicable to a cardiologist when the coronary artery was perforated during the cathet-erization procedure and during subsequent complications that occurred.

The report also did not establish or even assert that Dr. Mangin’s alleged breaches pertained to a subject matter that is common to and equally recognized and developed in all fields of medical practice, such that no specific cardiological knowledge or experience would be required to offer a relevant opinion. See Broders, 924 S.W.2d at 153; Keo, 76 S.W.3d at 732. Whether a cardiologist who is providing cardiac care to a patient should have sought help from a cardiac surgeon necessarily would depend on what medical care the cardiologist was capable of providing. This implicates a cardiologist’s judgment relative to his specialty and is not something common to and equally recognized and developed in all fields of medicine. To the extent that Dr. Mem-on in fact possesses knowledge as to when a cardiologist should seek assistance from a cardiac surgeon, the basis of such knowledge was not clearly articulated in his report and CV.

Op. at 709.

The majority cites no authority for the level of detail it requires to satisfy itself as to whether Dr. Memon is qualified to opine on the standards of care relevant to Wendt’s cardiological care, and the majority opinion disregards both the abuse of discretion standard for reviewing an expert report set out in Jelinek, Palacios, and other cases and the standard set out in Broders for assessing the credentials of a physician who is opining as an expert in a field outside his own. The majority specifically recognizes that both Dr. Memon’s report and his CV show that he is “certified by the American Heart Association as an Advanced Cardiac Life Support Provider,” and he has been “certified by the American Heart Association as a Health*732care Provider (C.P.R. and AED).” Op. at 709, But it ignores Dr, Memon’s. further statement:

I also am familiar with and have substantial knowledge of the causal relationship between an anesthesiologist’s and general and traumatic surgeon’s failures to meet the reasonable, prudent, and accepted standards of medical care and supervision in the diagnosis, care, and treatment of patients requiring ventilation and/or undergoing general anesthesia for cardiac surgical procedures under both planned and emergent conditions.

Thus, I cannot agree with the. majority’s conclusion, that, “[a]lthough Dr. Memon stated that he has provided anesthesia to patients undergoing cardiac procedures, he did not show that his ‘expertise goes to the very matter on which he or she is to give an opinion.’ ” Op. at 710 (quoting Broders, 924 S.W.2d at 153).

Nor can-I agree with the majority’that “[ujnder the specific- facts presented -here, Dr. Memon’s report is deficient because it fails to adequately link the education and experience listed on his CV, his statement that he is familiar with complications that may arise during the treatment of myocardial infarction, and. his specific opinions about how Dr. Mangin’s alleged errors caused Donald Wendt’s death,” Id. Nor can I find the “logical gaps” the majority claims cannot be filled in by inference. Id. (citing Scoresby, 346 S.W.3d at 556).

I would heed the supreme court’s admonishment that, in determining whether an expert is qualified, we. must not draw expert qualifications “too narrowly.” Larson v. Downing, 197 S.W.3d 303, 305 (Tex. 2006). Dr, Memon’s report and CV demonstrated that he had experience with the type of treatment Wendt received here and that he was familiar, with the applicable standards of care. This is sufficient to qualify him to offer his opinion in this case. See Hillery v. Kyle, 371 S.W.3d 482, 487 (Tex.App.-Houston [1st. Dist.] 2012, no pet.) (concluding that expert was qualified when he stated familiarity “with the standards of care relevant to the condition involved in this claim” and had “diagnosed 'and treated patients with conditions similar to those experienced by” plaintiff); Rittger v. Danos, 332 S.W.3d 550, 558 (Tex.App.-Houston [1st Dist.] 2009) no pet.) (focusing on condition involved in claim rather than defendant doctor’s area of expertise).

The fact that Dr. Memon is an anesthesiologist who routinely works in eardiotho-racic settings involving “the diagnosis, care, and treatment of patients requiring ventilation and/or undergoing general anesthesia for cardiac surgical procedures under both planned and emergent conditions,” but is not -a cardiologist, does not disqualify him as an expert as to either the cath lab cardiologist or the cath lab anesthesiologist in this case. See Rittger, 332 S.W.3d at 558; see also Hayes v. Carroll, 314 S.W.3d 494, 504-05 (Tex.App.-Austin 2010, no pet.) (holding board certified vascular surgeon was qualified to render opinion on standard of care applicable to emergency room doctor); Blan v. Ali, 7 S.W.3d 741, 746-47 (Tex.App.-Houston [14th Dist.] 1999, no pet.) (holding that neurologist was qualified as expert on plaintiffs condition — stroke—even though defendant doctors were emergency room doctor and cardiologist).

The majority, however, finds only that the report was “an objective good faith effort to comply” with the standards for an expert report set out in section 74.351, in that it “summarizes Dr. Memon’s opinions on the applicable standards of care, identifies the ways inwhich he believes that Dr. Mangin breached those:, standards, and provides an explanation of how these alleged breaches - caused Donald Wendt’s *733death” while still finding it “defieien[t] in failing to articulate how Dr. Memon’s expertise qualified him to render an opinion relevant to the claims against Dr. Mangin.” Op. at 710.

Because I would conclude, unlike the majority, that Dr. Memon’s opinion does, in fact, satisfy the requirements of section 74.351, I would not go looking behind obviously qualifying credentials to find some “logical gap” that failed to show how he was qualified to opine as he did. Indeed, the Texas Supreme Court has cautioned against exactly that. See Broders, 924 S.W.2d at 151 (holding that absent clear abuse of discretion, supreme court will not disturb trial court’s ruling on qualification of expert witness). And I certainly would not do scrutinize an expert’s credentials and find them inadequate on the basis of a description of his report that mischaracter-ized what he was actually saying. Thus, for all these reasons, I 'cannot join the majority’s opinion that Dr. Memon’s expert report with respect to Dr. Mangin was deficient, and I would not remand the case for the Wendts to attempt to cure the “deficiency” as their sole avenue for avoiding dismissal of Dr. Mangin — -the cardiologist whose acts initiated Wendt’s immediate need for aeration of the blood to his brain — with prejudice.

Conclusion

The majority opinion in this ease presents a very serious encompassing question for,-review: whether the standard for reviewing a trial court’s determination of the adequacy of medical expert repqrts and the adequacy of expert credentials is still an abuse of discretion standard or whether this Court is correct to subject the reports to a much more exacting de novo appellate review. And it raises the further critical question of what standard of review applies to expert reports when, the proximate cause of a patient’s death or injury is not just one negligent act by one physician but a series of negligent acts by different medical ¡personnel together directly and fore-seeably caused the death or injury giving rise to the claim.

The majority itself accurately points out that “[t]he requirement to serve an expert-report arises at the outset of litigation and before the opportunity for the plaintiff to engage in significant. discovery, including the taking of oral depositions of the defendants,” and, thus, “the amount and quality of evidence available at the time of drafting the expert reports will be less than that available at trial on the merits or even the summary-judgment stage.” Op. at 713 (citing Tex. Civ. Prac. & Rem. Code Ann. § 74.351(a), (s), Wright, 79 S.W.3d at 52 (the report “need not marshal all the plaintiffs proof’), and Palacios, 46 S.W.3d at 878). Yet the majority’s requirements for expert reports disregard these criteria and the reasoning behind them, with the result that at least as much, if not more, is demanded of the expert report than at the summary judgment or trial stage.

-This is a case in which several physicians were participants in a chain of events that began with one physician’s negligence — the perforation of the patient’s artery by the cardiologist inserting a stent and the resulting pooling of blood around his heart causing the heart to be unable to pump — and ended with "that patient’s death due to prolonged loss of oxygen to the brain, caused not only by the negligent actions of at least the cardiologist but also by the negligence of at least the anesthesiologist in charge. All of the testifying experts clearly stated that the negligent actions of both defendants were substantial factors in the patient’s death. The question for the courts, therefore, is whether, in such a case, to survive the threshold requirements of informing the *734defendant of the specific conduct the plaintiff has called into question and providing a basis for the trial court to conclude that the claims have merit, the plaintiff must marshal all of his proof as to who did exactly what exactly when — in advance of discovery — rather than seeking discovery from the defendants who have this information and then trying the case in the courts.

The purpose of the expert report requirements of Civil Practice and Remedies Code sections 74.351 and 74.401 is to deter frivolous suits, not to create an unreasonably high barrier to filing suit. The very strict reading applied by the majority to the expert reports in this case will lead to dismissal with prejudice of suits that appear meritorious before discovery can be had on the merits and trial can test the actual merits of the plaintiffs claim. To my mind, the majority has lost sight of both the statutory standard for adequacy of expert reports and the standard of appellate review of a trial court’s determination as to adequacy. And it has lost sight of the reason for those standards — to assure that meritorious suits rather thant frivolous ones go on to discovery and trial.

I would affirm the order of the trial court denying both Dr. Mangin’s and Dr. Wojciechowski’s motions to dismiss, and I would remand the case for trial against both doctors without requiring the Wendts to “cure the deficiency” in Dr. Memon’s expert report served on Dr. Mangin.

OPINION

This is an interlocutory appeal from a trial court’s order ruling that the medical expert reports filed in support of a medical malpractice lawsuit are sufficient to allow the case to proceed against Doctors Earl Mangin, Jr. and Zbigniew Wojciechowski. Both doctors appeal from the trial court’s denial of their motions to dismiss.

Because the expert report was deficient as to Dr. Mangin, we reverse the trial court’s order denying his motion to' dismiss, and we remand with instructions to the court to provide, the Wendts an opportunity to cure the deficiency in accordance with the statute. Because the expert reports were adequate as to Dr. Wojciechow-ski, we affirm the trial court’s denial' of his motion to dismiss.

Background

Donald Wendt was admitted to Sugar Land Methodist Hospital with chest pain. Interventional cardiologist Dr. Earl Man-gin, Jr. performed an angioplasty and implanted a stent, but during the procedure he perforated an artery. An anesthesia provider responded to a call for assistance, administered anesthesia, and attempted to establish ventilation by intubating the patient, but at first the tube was mistakenly inserted into the esophagus. Mr. Wendt’s oxygen levels dropped to 70%,' and he. experienced cardiac arrest. Ventilation was established by alternative methods, and surgery was performed to correct the perforated artery and other' complications. Unfortunately, the loss of oxygen caused irreparable brain damage, and Mr. Wendt died two days later.

Wendt’s estate and his two daughters (collectively, the Wendts) sued the hospital and Dr.' Mangin, Dr. Zbigniew Wojcie-chowski, and “Dr. Smith.” The petition alleged that a medical record indicated that “a ‘Smith? was an anesthesiologist during the relevant periods,” although no information or address for a “Dr. Smith working for or in Hospital” could be located. The petition specifically alleged that “upon inquiry Hospital staff stated that there was no Smith and Wojciechowski *705was the anesthesiologist during the entire relevant time,” and that “Dr. Wojciechow-ski improperly, intubated .Plaintiff placing the tube in a manner that blocked Plaintiffs ability to breath, placing the tube" in his esophagus.” The petition additionally alleged that Dr. Wojciechowski “prepared and signed the anesthesia report indicating he was present during the procedure.”

In an attempt to comply with Chapter 74 of the Texas Civil Practice and Remedies Code, the Wendts timely filed three expert reports. Both appellant doctors filed motions to dismiss the Wendts’ claims challenging the adequacy of the expert reports. As to both motions, the- Wendts argued in response that their reports were sufficient, and, in the alternative, the court should grant a 30-day extension to cure the reports because they had made a good-faith attempt to comply with the statute. After the motions to dismiss were filed, Dr. Wojciechowski served a discovery response indicating that Dr. Milan Sheth was the anesthesiologist who cared for Mr. Wendt and improperly intubated him.1

The trial court denied both doctors’ motions, and both doctors appealqd.

Analysis

The appellant doctors filed separate briefs and raised distinct arguments asserting that the court erred by denying their motions to dismiss.

A plaintiff asserting health care liability claims must serve each defendant physician or health care provider with one or more expert reports and a curriculum vitae of each expert whose opinion is offered to substantiate the merits of the claims. See Tex Civ. Prac. & Rem. Code § 74.351(a), (i); TTHR Ltd. P’ship v. Moreno, 401 S.W.3d 41, 42 (Tex. 2013). The statute requires that such a report must provide: (1) “a. fair summary of the expert’s opinions ... regarding applicable standards of care,” (2) a statement identifying “the manner in which the- care rendered by the physician or health care provider failed to meet the standards,” and (3) an explanation of. “the causal relationship between that failure and the injury, harm, or damages claimed.” Tex. Civ. Prac. & Rem. Code § 74.351(r)(6); see TTHR Ltd. P’ship, 401 S.W.3d at 44. “The expert report need not marshal every bit of the plaintiffs evidence,” Jernigan v. Langley, 195 S.W.3d 91, 93 (Tex. 2006), but it must “explain, to a reasonable degree, how and why the breach caused the injury based on the facts presented.” Jelinek v. Casas, 328 S.W.3d 526, 539-40 (Tex. 2010).

When a defendant timely files a motion to dismiss challenging the adequacy of an expert report, the trial court may take one of three actions. First, if the court concludes that the report is adequate, it may deny the motion to dismiss. See, e.g., Hillery v. Kyle, 371 S.W.3d 482, 492 (Tex.App.-Houston [1st Dist.] 2012, no pet.). Second, if. the court concludes that the report does not constitute an objective good faith effort to comply with the statute, it must grant the motion to dismiss. See Tex. Civ. Prac. & Rem.Code § 74.351((); Bowie Mem. Hosp. v. Wright, 79 S.W.3d 48, 51-52 (Tex. 2002); see also Jernigan, 195 S.W.3d at 94. Third, if the court concludes that the report is an objective good faith effort to comply with the statute but it is nevertheless deficient in some *706way, it may grant the plaintiff one 30-day extensión to cure the deficiency. See Tex. Civ. Prac. & Rem. Code § 74.351(c); Scoresby v. Santillan, 346 S.W.3d 546, 557 (Tex. 2011), Because the “purpose of the expert report requirement is to deter frivolous claims, not to dispose of claims regardless of their merits,” the Supreme Court has held that “trial courts should be lenient in granting thirty-day extensions and must do so if deficiencies in an expert report can be cured within the thirty-day period.” Scoresby, 346 S.W.3d at 554. In addition, “when the court of appeals finds deficient a report that the trial court considered adequate,” the plaintiff should be afforded one 30-day extension to cure the deficiency, if possible. Leland v. Brandal, 257 S.W.3d 204, 207 (Tex. 2008).

A report qualifies as an objective good faith effort to comply if it (1) informs the defendant of the specific conduct the plaintiff questions, and (2) provides á basis for the trial court to conclude that the plaintiffs claims have merit. Loaisiga v. Cerda, 379 S.W.3d 248, 260 (Tex. 2012); accord Scoresby, 346 S.W.3d at 549. Because the expert report must set forth the relevant facts upon which the expert relies, identify the" applicable standards of care, and explain how the defendant’s breach caused the claimant’s injuries, the Supreme Court of Texas has held that a court ordinarily may look only to the “four comers” of the expert report to determine whether it constitutes an objective good faith effort to comply. Wright, 79 S.W.3d at 52; Am. Transitional Care Ctrs. of Tex., Inc. v. Palacios, 46 S.W.3d 873, 878 (Tex. 2001). When the question of adequacy hinges on the expert’s qualifications, the court may also consider the four corners of the expert’s curriculum vitae. See Palacios, 46 S.W.3d at 877 (noting that the inclusion of a curriculum vitae is also required by statute); Woodard v. Fortress Ins. Co., No. 01-14-00792-CV, 2015 WL 1020193, at *1 (Tex.App.-Houston [1st Dist.] Mar. 5, 2015, pet. denied) (mem.op.).

We review a trial court’s ruling on a motion to dismiss pursuant to Section 74.351 for abuse of discretion. Palacios, 46 S.W.3d at 878. A trial court abuses its discretion if it acts in an arbitrary or unreasonable manner without reference to any guiding rules or principles. Walker v. Gutierrez, 111 S.W.3d 56, 62 (Tex. 2003). In exercising its discretion, a trial court should review the reports, resolve any inconsistencies, and determine whether the reports demonstrate a good faith effort to show that the,plaintiffs claims have merit. Van Ness v. ETMC First Physicians, 461 S.W.3d 140, 144 (Tex. 2015) (per curiam).

I. Earl Mangin, Jr., M.D.

Dr. Mangin, the cardiologist, argues that the trial court erred by denying his motion to dismiss for want of an expert report. The Wendts provided expert reports from three physicians: (1) Dr. William J. Maz-zei, an anesthesiologist; (2) Dr. Paul W. Dlabal, a practicing cardiologist; and (3) Dr. Abdul Q. Memon, a board certified anesthesiologist. With respect to the claims against Dr. Mangin, two of these reports are not objective good faith efforts to comply with the statute. Dr. Mangin argues that the third report which does offer opinions about him, Dr. Memon’s report, is wholly inadequate because he is not qualified to render an opinion.

A. Mazzei and Dlabal reports

Dr. Mazzei’s report made no assertions and drew no conclusions relevant to Dr. Mangin or to any cardiologist generally. As such, standing alone this report did not satisfy any of the three statutory expert report requirements as to Dr. Mangin. See Tex. Civ. Prac. & Rem. Code § 74.351(r)(6).

*707Dr. DlabaFs report reviewed and summarized the medical records from the two days Mr. Wendt was in the hospital before his death. He opined that the cause of death was loss of oxygen to the brain, a consequence of complications of treatment for a heart attack — in particular the perforation of a coronary artery. As to causation, he wrote: “The primary cause of death was cerebral anoxia. Had coronary perforation and its attendant complications not occurred in the course of treatment, the underlying condition was, in reasonable medical probability, survivable.” This report fails to satisfy the statutory requirements because it did not identify any applicable standards of care, assert that Dr. Mangin failed to comply with an applicable standard' of care, or explain how a departure from an applicable standard of care caused Mr. Wendt’s death. See id. Because Dr. Dla-bal’s report merely summarized the medical records, it did not inform Dr. Mangin of the conduct that the plaintiffs had questioned nor did it provide a basis for the trial court to conclude the claims have merit. See Palacios, 46 S.W.3d at 879.

B. Deficiencies in Dr. Memon’s report

Finally, we consider the report of Dr. Memon, an anesthesiologist. Dr. Man-gin contends that this report is deficient and does not constitute an objective good faith effort because Dr. Memon is not qualified to render an expert opinion about his performance of heart surgery.

When a claimant, sues a physician, the petition must be supported by an expert report from a physician who. is qualified to testify as an expert witness on the question of whether the defendant departed from an accepted standard of medical care causing the alleged damages. See Tex. Civ. Prac. & Rem. Code § 74.351(r)(5); id. § 74.401; Mettauer v. Noble, 326 S.W.3d 685, 691 (Tex.App.-Houston [1st Dist.] 2010, no pet.). In particular, the expert must (1) be practicing medicine at the time he testifies or when the claim arose, (2) have “knowledge of accepted standards of medical care for the diagnosis, care, or treatment of the illness, injury, or condition involved in the claim,” and (3) be “qualified on the basis of training or experience tó offer an expert opinion regarding those accepted standards of medical care.” Tex. Civ. Prac. & Rem. Code § 74.401(a). To determine whether a witness is qualified based on his training and experience, a trial court must consider whether the witness is “board certified or has other substantial training or experience in an area of medical practice relevant to the claim,” and whether he “is actively practicing medicine in rendering medical care services relevant to the claim.” Id. § 74.401(c).

Not every licensed physician is qualified to testify about every medical question. Broders v. Heise, 924 S.W.2d 148, 152 (Tex. 1996); see Tenet Hosps. Ltd. v. Barajas, 451 S.W.3d 535, 541 (Tex.App.-El Paso 2014, no pet.). The critical inquiry is “whether the expert’s expertise goes to the very matter on which he or she is to give an opinion.” Broders, 924 S.W.2d at 153. Thus a physician may be qualified to provide an expert report even when his specialty differs from that of the defendant “if he has practical knowledge of what is usually and customarily done by other practitioners under circumstances similar to those confronting the malpractice defendant,” or “if the subject matter is common to and equally recognized and developed in all fields of practice.” Keo v. Vu, 76 S.W.3d 725, 732 (Tex.App.-Houston [1st Dist.] 2002, pet. denied).2

*708In his report, Dr. Memon stated that the applicable standards of care required Dr. Mangin to be prepared to “promptly deal with” a ruptured-artery and cardiac -tam-ponade, both of which are known complications of a stent insertion, and to call for specialists such as an anesthesiologist or cardiac surgeon “as soon as any problem is apparent.”3 With respect to the first of these proposed standards of care, Dr. Memon’s report raised a question about whether Dr. Mangin knew how to drain a tamponade, but he did not actually offer an opinion that Dr, Mangin was unqualified to perform a stent insertion.4 The report thus suggested that Dr. Mangin may have erred by choosing to perform a risky procedure if he was unqualified to perform it. With respect to the proposed duty to call for specialists, Dr. Memon observed that Dopamine was administered to Mr. Wendt at 3:45 am. He characterized the administration of Dopamine as “a sigh” that Mr. Wendt “was in cardiac distress” and had “low blood pressure.” Four minutes later, at 3:49 am, an anesthesiologist was called, but an additional 21 minutes passed before a cardiac surgeon was called at 4:10 am. Dr. Memon’s report opined that if Dr. Mangin had promptly- noticed the ruptured artery, performed .pericardiocentesis, and maintained blood flow to' the brain, Mr. Wendt “would not have suffered the period of hypoxia that left him brain dead.” The opinions in the report relating to both of these suggested standards of care implicate the qualifications required for, and the adequacy of performance of, heart surgery relating'to inserting a stent and managing complications of that procedure.

We must determine whether Dr. Mem-on’s report and curriculum vitae demonstrate that he is qualified to offer specific expert opinions despite the fact that he is neither board certified in nor actively practicing cardiology. See Tex. Civ. Prac. & Rem. Code § 74.401(c). Dr. Memon is a board-certified anesthesiologist with extensive experience in anesthesiology and pain management. He is licensed in five states, has practiced in Texas since 1977, and is “familiar with the standards of care that [apply] to, physicians and institutions in Texas.” His report stated that he is experienced in the administration of anesthesia *709and intubation of patients during surgical procedures.

Dr. Memon’s attached CV shows extensive education and experience in the areas 6f anesthesiology and pain management. He has experience with “preoperative evaluation, airway management, including placement of an Endotracheal tube (‘ETube’), and administration of anesthesia to patients undergoing surgical procedures, including cardiac procedures.” In addition to his stated education and training in the field, of anesthesiology, he . also asserted that he is “familiar with the possible complications that can arise. during treatment of an acute myocardial infarction and the remedial measures necessary if such complications arise,” and that he has “substantial knowledge of the causal relationship between an anesthesiologist’s and general and traumatic surgeon’s fail-, ures to meet the reasonable, prudent, and accepted standards of medical care and supervision in the diagnosis, care and treatment of patients requiring ventilation and/or undergoing jgeneral anesthesia for cardiac surgical prócedures under both-planned and emergent conditions.”

Although he asserts familiarity with standards of .care for “general and traumatic surgeons,” Dr. Memon does not make any assertions of expertise pertaining to a cardiologist’s duties when providing cardiac care.- The report also does not explain whether and how Dr. Memon’s knowledge about the standards applicable to “general and traumatic surgeons” applied to the specific breaches that he attributes to Dr. Mangin. Moreover, Dr. Memon’s statement that he is .“familiar” with the complications that can arise during treatment for acute myocardial infarc* tion and the treatménts for such complications is vague and non-specific. In sum, thfe expert report does not demonstrate how Dr. Memon’s knowledge, skill, experience, training, or education qualified him to render an opinion about the particular breaches of the. standard of care applicable to a cardiologist when the coronary artery was, perforated during the catheterization procedure and during subsequent complications that occurred.

The report also did not establish or even assert that Dr. Mangin’s alleged breaches pertained to a subject matter that is common to and equally recognized and developed in all fields of medical practice, such that no specific cardiological knowledge or experience would be required to offer a relevant opinion. See Broders, 924 S.W.2d at 153; Keo, 76 S.W.3d at 732. Whether a cardiologist who is providing cardiac care to a patient should have sought help from a cardiac surgeon. necessarily would depend on what medical care the cardiologist was capable-of providing.- This implicates a cardiologist’s judgment relative to his specialty and is not something common to- and equally recognized and developed in all fields of medicine. .To the extent that Dr. Memon in fact possesses knowledge as to when a cardiologist, should seek assistance from a cardiac surgeon, the basis of such knowledge was not clearly articulated in his report and CV.

Both Dr. Memon’s report and his CV show that he is “certified by the American Heart Association as an Advanced Cardiac Life Support Provider,” and he has been “certified by the American Heart Association as a Healthcare Provider (C.P.R. and AED).”' But neither the report nor the CV explain what it means for an anesthesiologist to be certified by the American Heart Association as an Advanced Cardiac Life Support Provider or- Healthcare Provider or how these certifications would qualify Dr. Memon to opine, as he did, that Dr. Mangin breached a standard of care by. the manner in which he managed complications of the stent insertion or by the *710alleged delay in seeking assistance from other specialists.

The Wendts argue that Dr. Memon cannot be disqualified simply because his area of specialization differs from Dr. Mangin’s, and they emphasize that his report states that he has extensive experience practicing as an anesthesiologist in cardiac cases. But as we have explained, the expert report did not demonstrate that Dr. Memon has “substantial training or experience” in cardiology or management of cardiac complications. Although Dr. Memon stated that he has provided anesthesia to patients undergoing cardiac procedures, he did not show that his “expertise goes to the very matter on which he or she is to give an opinion.” Broders, 924 S.W.2d at 153.

Under the specific facts presented here, Dr. Memon’s report is deficient because it fails to adequately link the education and experience listed on his CV, his statement that he is familiar with complications that may arise during the treatment of myocardial infarction, and his specific opinions about how Dr. Mangin’s alleged errors caused Donald Wendt’s death. Such logical gaps cannot be filled by inference. See Scoresby, 346 S.W.3d at 556 (holding that omissions from expert report may not be supplied by inference).

C. Objective good faith effort

Dr. Mangin argues that the report’s deficiency in articulating Dr. Mem-on’s qualifications means that it did not constitute an objective good faith effort to comply with the statute. As such, he contends that the court wqs required to grant his motion to dismiss.

While we agree the report was deficient, we are not convinced that dismissal was required on this record. The Supreme Court often has cautioned that the statutory expert report requirements exist in part “to deter frivolous claims, not to dispose of claims regardless of their merits.” Scoresby, 346 S.W.3d at 554; see Certified EMS, Inc. v. Potts, 392 S.W.3d 625, 631 (Tex. 2013); Loaisiga, 379 S.W.3d at 258. Consequently, the Court has admonished trial courts to be lenient in granting 30-day extensions. See Scoresby, 346 S.W.3d at 554.

Here the trial court found that the report was adequate. Indeed the report summarizes Dr. Memon’s opinions on the applicable standards of care, identifies the ways in which he believes that Dr. Mangin breached those standards, and provides an explanation of how these alleged breaches caused Donald Wendt’s death. See Tex. Civ. Prac. & Rem. Code § 74.351(r)(6). Accordingly, we conclude that the report was an objective good faith effort to comply, despite its deficiency in failing to articulate how Dr. Meihon’s expertise qualified him to render an opinion relevant to the claims against Dr. Mangin.

We have reached this conclusion on interlocutory appeal from the trial court’s denial of the defendant’s motion to dismiss. Because we have found deficient a report that the trial court considered adequate, on remand the Wendts should be afforded a 30-day extension to cure the deficiency, if possible. See Leland, 257 S.W.3d at 207. We sustain Dr. Mangin’s first issue, and we reverse the trial court’s order denying his motion to dismiss.

II. Zbigniew Wojciechowski, M.D.

In one issue, Dr. Wojciechowski argued that the trial court erred by denying his motion to dismiss because the reports were so deficient as to constitute no report as to him. In particular, he contends that he was not the anesthesiologist who improperly intubated Mr. Wendt. He argues that he cared for Mr. Wendt only in the operating room, and none of the expert *711reports implicate anything he did. He also argues that two of the reports do not mention'him by name and the third report establishes that he is the wrong party.

A. Dr, Memon’s report

Dr. Memon’s report is the one that Dr. Wojcieehowski contends exonerates him. Dr. Memon stated that Mr. Wendt was without oxygen for “significant periods of time,” and he identified improper placement of the endotracheal tube as a contributing cause for the loss of oxygen. The report noted that “Dr. Mangin’s record states that the anesthesiologist incorrectly placed the [endotracheal tube] in the esophagus ... and does not mention how long it took Dr. Smith1 to notice and correct the placement.” In the footnote referenced immediately after the name “Dr. Smith,” Dr. Memon’s report elaborated that the medical records were unclear as to the actual identity of the anesthesiologist who performed that procedure. .He stated:

Of note, while the records show that Dr. Wojcieehowski was the anesthesiologist of record during cardiac surgery performed in the operating room and was present for the administration of general anesthesia and throughout that treatment on the morning of February 7, 2012, the nurse’s notes from the cathet-erization lab reference that Dr. Smith had arrived, intubation was attempted, and Dr. Smith was to complete the notes on intubation. While the signature on the handwritten anesthesiology report is difficult, if not illegible, it is logical that it was prepared by the Dr. Smith who was called to the cath lab by Dr. Mangin and who performed the procedures prior to Donald Wendt’s transfer to the operating room. Further, if an anesthesiologist was not present at the time of the initial intubation attempt, that of itself could be a serious departure from the standard of care and shift liability on the doctor who proceeded before the anesthesiologist was present.

Dr. Wojcieehowski asserts that this shows that he. was not the anesthesiologist who performed the intubation. But Dr. Memon’s report is not conclusive on the issue of the relevant anesthesiologist’s identity. Dr. Memon referenced “Dr. Smith” as the doctor who performed the intubation procedure, although that identification was expressly qualified by the footnoted explanation that he was drawing an inference about identity based on the sparse' and partially illegible information in the record.

B. Dr. Mazzei’s report

Dr. Wojcieehowski also argues that Dr. Mazzei’s report is “no report” as to him because it does not mention him by name. Dr. Mazzei’s report summarized relevant medical- records, identified standards of care applicable to an anesthesiologist, asserted that the anesthesia provider departed from those standards of care, and explained how those departures caused Mr. Wendt’s death.

When a health care liability claim is based on an assertion of direct liability, the expert report typically will identify the defendant by name. See Mem’l Hermann Surgery Ctr. Tex. Med. Ctr., L.L.P. v. Smith, No. 01-12-00393-CV, 2012 WL 6645017, at *4 (Tex.App.-Houston [1st Dist.] 2012, pet. ref'd). However, the statute does not specifically require the defendant physician to be identified by name, see Tex. Civ. Prac. & Rem. Code § 74.351(r)(6), and in some circumstances Texas courts have held that the mere omission of a defendant’s name from an expert report did not render it “no report.” See, e.g., Gardner v. U.S. Imaging, Inc., 274 S.W.3d 669, 671-72 (Tex. 2008) (when a *712party’s alleged liability is vicarious, a report that implicates the conduct of a defendant or its employees is adequate); Ogletree v. Matthews, 262 S.W.3d 316, 317, 321-22 (Tex. 2007) (report implicated defendant doctor’s conduct “although it did not mention him by name”); Troeger v, Myklebust, 274 S.W.3d 104, 106, 110 (Tex.App.-Houston [14th Dist.] 2008, pet. denied) (expert report implicated conduct of sole defendant who was not identified by name but by position as “previous dentist” and by reference to specific conduct).

Dr. Mazzei’s report set forth the standards of care, breach, and causation with respect to the anesthesiologist who intu-bated Mr. Wendt. It recited that Dr. Mazzei is a board-certified anesthesiologist who frequently provides anesthesia for patients undergoing cardiac catheterization and who is “thoroughly familiar "With ventilation problems that" may arise in the course of an emergency.” Dr. Mazzei reviewed Mr. Wendt’s medical records and summarized them in his report. He set forth1 several standards of care for anesthesiologists caring for patients like Mr. Weridt. He wrote:

When a patient requires emergency airway management as Mr. Wpndt did, the standard of care requires that the anesthesiologist quickly assess the patient’s condition, perform an evaluation of the airway, and bring the necessary and potentially needed equipment and drugs to ventilate and intubate the patient.

Dr. Mazzei explained that because of the bleeding from the perforation in Mr. Wendt’s coronary artery, “the standard of care required that [he] be immediately in-tubated.” He opined that this., should be done under anesthesia to simplify visualization of the airway. He explained that because the paralysis from anesthesia would leave a patient unable to breathe on his own, “the standard of care requires that a patient receive 100% oxygen for several minutes prior to induction of anesthesia.” In addition, “the standard of care requires that the anesthesiologist maintain the patient’s oxygen level at a sufficiently high level so as to prevent organ damage.”

Dr. Mazzei explained that the medical records showed proper preoxygenation and induction of anesthesia, but “the anesthesia provider was unable to intubate ’... and during those' attempts the [oxygen] saturation fell to 88%.” When the “anesthesia provider” attempted mask ventilation, Mr. Wendt’s oxygen saturation “fell into the 70s, a level at which organ damage starts to occur.” Dr. Mazzei opined that it was this low oxygen saturation that caused Mr. Wendt to experience cardiac arrest. He further opined that the low saturations were caused' by inadequate ventilation, which in turn was caused by the anesthesia provider’s taking “too much time to reestablish adequate ventilation.” Dr. Maz-zei wrote, “This was below the standard of care and led to Mr. Wendt’s anoxic brain damage and subsequent demise.” Dr. Mazzei summarized his conclusions, saying that the anesthesia provider:

induced anesthesia which stopped Mr. Wendt from breathing on his own, but then failed to re-establish sufficient ventilation before a cardiac arrest occurred. This failure was below the standard of care and was the proximate cause of the cardiac arrest that led to anoxic brain damage and ultimate demise.

Dr. Mazzei’s report satisfied the statutory requirements for an expert report , by setting forth the applicable standards of care, identifying how the anesthesia provider breached those standards, and explaining how the alleged breaches caused Mr. Wendt’s death. See Tex. Civ. Prac. & Rem. Code § 74.351(r)(6). In addition, the report and CV showed that Dr. Mazzei was qualified to render such an opinion. *713Although this report did not specifically identify Dr. Wojciechowski by name, it identified with particularity the responsible party by function: the anesthesia provider who intubated Mr. Wendt. See Ogletree, 262 S.W.3d at 321-22 (report implicated an unnamed doctor when directed solely to the care performed by the doctor); Troeger, 274 S.W.3d at 106, 110 (reference to “previous dentist” implicated sole defendant such as to require an objection to the adequacy of the report); Maris v. Hendricks, 262 S.W.3d 379, 384-85 (Tex.App.-Fort Worth 2008, pet. denied) (expert report sufficiently implicated conduct of physician’s assistant who was not identified by name to constitute good-faith effort to comply with the statute).

Dr. Wojciechowski relies on several precedents from intermediate courts of appeals to support his argument that the reports did- not implicate his conduct because he was not identified “by name or otherwise.” In each of these cases, however, the absence of the defendant’s name was not the sole reason for finding that his or her conduct was not implicated by the report.5 Moreover, the reports in this case constituted a good faith effort to comply with the statute because they informed Dr. Wojciechowski of the specific conduct the plaintiffs called into question and provided a basis for the trial court to conclude that them claims had merit. E.g., Potts, 392 S.W.3d at 630.

The requirement to serve an expert report arises at the outset of litigation and before the opportunity for the plaintiff to engage in significant discovery, including taking oral depositions of the defendants. See Tex. Civ. Prac. & Rem. Code § 74.351(a) (report must be served no later than 120 days after the defendant’s answer is filed); id. § 74.351(s) (limiting discovery until after claimant serves the expert report). As such, the statute Itself contemplates that the amount and quality of .evidence available at the time of,drafting the expert reports will be less than that available at trial on the merits or even the summary-judgment stage. Cf. Wright, 79 S.W.3d at 52 (the report “need not marshal all the plaintiffs proof’); Palacios, 46 S.W.3d at 878.

The alleged deficiency of which Dr. Wo-jciechowski complains arises from a question of fact presented by the medical records themselves: who was the doctor who performed the intubation? In reliance on those records, the expert reports in this case acknowledge and explain the factual ambiguity as to the identity of the anesthesiologist, but they do not attempt to resolve it. For example, Dr. Memon’s report explains that Dr. Wojciechowski is listed as the anesthesiologist of record but states that other facts in the records suggested a “Dr. Smith” was the person who performed the intubation in the catheteri-zation lab. But the reports do identify the *714anesthesia provider by function and explain how that doctor’s negligence contributed to Mr. Wendt’s death.

This factual ambiguity about the identity of the anesthesiologist does not affect our conclusion that the reports satisfied the statutory requirements, or in any event, constituted an objective good faith effort to comply. A trial court is required to grant a motion to dismiss only when “the report does not represent an objective good faith effort to comply.” Tex. Civ. Prac. & Rem. Code § 74.351(l). In light of the standard of review, we cannot conclude that the court abused its discretion by denying Dr. Wojciechowski’s motion to dismiss.

Moreover, in their briefing on interlocutory appeal the parties have suggested that further discovery has led to a resolution of the factual ambiguity regarding the identity of the responsible anesthesiologist. Because this is an interlocutory appeal, our disposition of this case does hot end the litigation but instead returns the parties to the district court to proceed to trial on the merits or avail themselves of other procedural avenues for seeking dismissal if there is evidence conclusively showing that the wtong party has been sued. See, e.g., Tex. R. Civ. P. 166a.

We hold that the trial court did not err by denying Dr. Wojciechowski’s motion to dismiss, and we overrule his sole issue.

Conclusion

We reverse.the trial court’s denial of Dr. Mangin’s motion to dismiss, and we remand to the trial court to afford the Wendts a ,30-day extension to cure the deficiency as set forth in this opinion and for further proceedings. We affirm the trial court’s denial of Dr. Wojciechowski’s motion to dismiss, and we remand to the trial court for further proceedings.
