Transcatheter Valve-In-Valve Implantation In A Patient With A Degenerative Sutureless Aortic Bioprosthesis: Case Report And Literature Review

Sutureless aortic bioprostheses (SAB) provide shorter aortic cross-clamp time and cardiopulmonary bypass duration compared to conventional aortic valve replacement. Similarly to other bioprostheses, reintervention may become necessary in some cases because of long-term structural degeneration of the valve. Valve-in-valve (ViV) transcatheter aortic valve replacement may represent an effective and safe alternative to aortic valve replacement in patients with degenerated bioprostheses who carry a high risk for reintervention. We report the case of a self-expandable transcatheter ViV procedure in a degenerated SAB.
