Valve-in-valve transcatheter aortic valve implantation with fracturing of a failed small surgical aortic bioprosthesis: a case report

摘要

Failure of a small surgical aortic bioprosthesis represents a challenging clinical scenario with valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) often resulting in patient-prosthesis mismatch. Bioprosthetic valve fracture (BVF) performed as a part of the ViV TAVI has recently emerged as an alternative approach with certain types of surgical bioprostheses.
