Clinical Outcomes and Valve Performance of Intra-Annular Self-Expanding Transcatheter Aortic Valve in Valve-in-Valve Procedures: Insights From the NAViV Registry.
BACKGROUND Most evidence for transcatheter aortic valve replacement (TAVR) for valve-in-valve procedures comes from balloon-expandable and supra-annular self-expanding valves. However, data on intra-annular self-expanding valves remain limited. The objectives of this registry were to evaluate the short- and midterm out...
