Cardiothoracic surgery experts evaluate whether operative indication, technique, and perioperative management of the heart, great vessels, lungs, and esophagus met the accepted standard of care. Certification by the American Board of Thoracic Surgery (ABTS) is reached through one of four defined pathways, the most common being completion of a full five-year ACGME-accredited general surgery residency followed by an ACGME-accredited thoracic surgery residency, or completion of a six-year integrated thoracic surgery residency approved by the ACGME 16. A joint 4/3 general surgery and thoracic surgery training program satisfies the traditional pathway as well 2. Because the specialty operates on patients with limited physiologic reserve, the analytic question in litigation is rarely whether a complication occurred — it is whether the complication was a recognized risk that was properly disclosed, whether it was managed correctly once it appeared, and whether the operation should have been offered at all.
The ABTS also imposes explicit operative volume requirements that bear directly on an expert's qualification to opine. Residents must average 125 major operations per year across the thoracic portion of training, and they must satisfy their index case requirements entirely from a single declared pathway — cardiothoracic, general thoracic, or cardiac — without mixing across pathways 3. That structure matters in expert selection because an adult cardiac surgeon and a general thoracic surgeon may both be board certified in thoracic surgery while having materially different operative experience with the procedure at issue.
Cardiac surgery is one of the most intensively measured fields in American medicine, which changes what discovery looks like. The Society of Thoracic Surgeons Adult Cardiac Surgery Database contains more than 8.3 million procedures from more than 1,000 participating institutions and captures more than 97% of the cardiac surgery performed in the United States, supporting risk models for coronary bypass, isolated and multivalve procedures, tricuspid valve surgery, and valve replacement after transcatheter aortic valve replacement 4. Risk-adjusted expected mortality and morbidity are therefore usually available for the specific operation, which allows an expert to distinguish an outcome within the expected range from one that requires explanation, and makes participation and reporting practices themselves a subject of examination.
Operative decision-making is the second major front. The 2020 ACC/AHA valvular heart disease guideline sets out the profession's recommendations on the timing of intervention, choice between repair and replacement, mechanical versus bioprosthetic valve selection, transcatheter versus surgical approaches, and anticoagulation management for prosthetic valves 5. Cases regularly turn on whether the heart team evaluation was performed, whether the patient was a candidate for a less invasive option, and whether the risks of the chosen prosthesis — including lifelong anticoagulation or eventual structural valve deterioration — were disclosed in a way the patient could act on.
Technical and perioperative allegations round out the field. Common claims include failure to diagnose acute aortic dissection in the emergency department or on imaging; perioperative stroke attributed to aortic manipulation, cannulation, or embolic load; graft selection and anastomotic technique in coronary bypass; sternal wound infection and mediastinitis; injury to the recurrent laryngeal or phrenic nerve during thoracic and esophageal operations; anastomotic leak after esophagectomy; retained surgical items; and errors in cardiopulmonary bypass conduct, including perfusion pressure, temperature management, and de-airing. Thoracic surgery experts are also retained in product liability matters involving valves, grafts, ventricular assist devices, and surgical staplers, where the question is whether the device failed or the surgeon misused it.
The Society of Thoracic Surgeons Adult Cardiac Surgery Database holds more than 8.3 million procedures from more than 1,000 institutions and captures more than 97% of all cardiac surgery performed in the United States — meaning risk-adjusted expected outcomes usually exist for the exact operation in dispute.

FAQ
A qualified expert should be board certified by the American Board of Thoracic Surgery and have current or recent operative experience in the specific domain at issue. Board certification alone is not sufficient discrimination: ABTS trainees satisfy their index case requirements entirely within one declared pathway — cardiothoracic, general thoracic, or cardiac — so an adult cardiac surgeon and a general thoracic surgeon can hold the same certificate with very different experience in the operation being litigated.
These experts are retained in coronary bypass and valve surgery claims, missed aortic dissection cases, perioperative stroke and myocardial injury disputes, lung resection and esophagectomy complications, cardiopulmonary bypass and perfusion errors, and sternal wound infection cases. They also appear in product liability matters involving prosthetic valves, grafts, ventricular assist devices, and surgical staplers.
It usually supplies the benchmark. The STS Adult Cardiac Surgery Database captures more than 97% of United States cardiac surgery and supports risk-adjusted models for most major procedures, so an expert can compare the patient's predicted risk of mortality and major morbidity against the observed outcome. That comparison helps separate a bad result inside the expected range from one that calls for an explanation, and the institution's own participation data and outcome reports are frequently sought in discovery.
They generally turn on whether the alternatives were fairly presented. The 2020 ACC/AHA valvular heart disease guideline addresses timing of intervention, repair versus replacement, mechanical versus bioprosthetic valve choice, and transcatheter versus surgical approaches, so the expert analysis usually asks whether a heart team evaluation occurred, whether a less invasive option was available, and whether the long-term consequences of the selected prosthesis — including lifelong anticoagulation or eventual structural deterioration — were disclosed.
Rarely, and it depends on the jurisdiction. Many states impose same-specialty or same-practice requirements on standard-of-care testimony in medical malpractice, and cardiothoracic surgery is a distinct board-certified specialty with its own operative training requirements. Where the claim concerns general operative principles rather than the cardiac or thoracic procedure itself, the analysis may differ, so the qualification question should be resolved before an expert is retained.
In general, medical expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are clinical experience, forensic experience, academic qualifications such as Fellowships, clinical settings, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
