The volumes of two aortic valve replacements (AVR) procedures have changed dramatically over the past few years, with more transcatheter procedures now being performed than open surgical procedures. Four cardiac surgeons discuss the evolving trends in TAVR, why the changes are occurring, and what’s ahead for TAVR and SAVR. Wilson Y. Szeto, MD (University of Pennsylvania) moderates the discussion that also features Michael J. Mack, MD (The Heart Hospital Baylor Plano), John V. Conte, MD (Penn State University), and Thomas E. MacGillivray, (Houston Methodist).
