7 Identification of Coronary Artery Orifice to Prevent Coronary Complications in Bioprosthetic and Transcatheter Aortic Valve Replacement

摘要

Background: The aim of this study was to identify anatomical variations in coronary artery orifices among high-risk patients with a small aortic root undergoing bioprosthetic aortic valve replacement (BAVR) and transcatheter aortic valve replacement (TAVR) in order to prevent coronary orifice obstruction perioperatively.
