Abstract
Transcatheter aortic valve replacement (TAVR) has become more common than surgical aortic valve replacement since 2016, with over 200,000 procedures globally each year. As patients increasingly outlive their TAVR devices, managing these cases is a growing concern. Treatment options include surgical removal of the old TAVR device (transcatheter aortic valve [TAV] explant) or implantation of a new transcatheter aortic valve (redo TAV). Redo TAV is complex because of the unique designs of TAV devices; compatibility issues; and the need for individualized planning based on factors such as implant depth, shape, and coronary artery relationships. This review serves as a comprehensive guide for redo TAV, detailing the design characteristics of TAV devices, device compatibility, standardized terminology, and a structured approach for computed tomography analysis. It aims to facilitate decision making, risk identification, and achieving optimal outcomes in redo TAV procedures.
