Abstract

Transcatheter valve-in-valve implantation within dysfunctional surgical bioprosthesis has become an alternative to redo open-heart surgery. However, suitability for valve-in-valve implantation in the tricuspid position is often limited by large surgical valve sizes. We report a case of a transcatheter tricuspid valve-in-valve implantation with a 29-mm balloon-expandable prosthesis within a 33-mm failed bioprosthesis (exceeding manufacturer's sizing recommendations). Overexpansion of a 29-mm SAPIEN XT valve by 1-ml overfilling of the deployment balloon was successfully performed, with no valve dislocation/embolization or residual tricuspid regurgitation. This case illustrates the feasibility of tricuspid valve-in-valve procedures in selected patients with large failed tricuspid bioprostheses.
