Abstract
Background: In the context of extension of transcatheter aortic valve implantation (TAVI) indications to lower-risk patients, long-term durability of transcatheter aortic bioprosthetic valves (TABV) is a crucial issue. There is a paucity of data, especially beyond 5 years of follow-up. Recently, new definitions have been proposed to assess structural valve deterioration (SVD) and bioprosthetic valve failure (BVF).
