Surgeon Involvement in Transcatheter Aortic Valve Replacement in the United States: A 2016 Society of Thoracic Surgeons Survey.

BACKGROUND: The Society of Thoracic Surgeons (STS) surveyed cardiothoracic surgeon participants in its Adult Cardiac Surgery Database (ACSD) to learn the extent of surgeon involvement in transcatheter aortic valve replacement (TAVR) procedures.

METHODS: An electronic survey was delivered to 2,594 surgeons in June 2016. When the survey closed 2 weeks later, 487 completed surveys had been submitted for a response rate of 18.8%.

RESULTS: Among the 487 participants in the ACSD who responded to the survey, 410 (84.2%) reported that TAVR was performed at their institutions. Approximately three-quarters reported that they performed TAVR procedures as part of a heart team (77.5%; 313 of 404), cardiologists and cardiothoracic surgeons were jointly responsible for TAVR referrals (83.7%; 339 of 405), and TAVR programs were administered either jointly by the cardiology and cardiac surgery departments or exclusively by the cardiac surgery department (73.3%; 297 of 405). A majority were involved in the pre-, intra-, and postoperative care of patients undergoing TAVR, with 91.4% (370 of 405) reporting participation in multidisciplinary meetings, at least 50% regularly performing technical aspects in 10 of 11 conduct of operation categories, and 86.6% (266 of 307) caring for patients undergoing TAVR after the procedure.

CONCLUSIONS: Cardiac surgeons in the United States are active participants in the management of patients with aortic stenosis as part of the heart team. The STS survey found that not only were they actively involved in the treatment decision-making process but they also played a significant role in the valve procedure, including deployment and postprocedural care. The heart team model continues to evolve and should be expanded into other areas of structural heart disease.
