Simultaneous transcatheter tricuspid and mitral valve-in-valve replacement for the treatment of degenerated bioprosthetic valves.

Transcatheter valve-in-valve replacement has become a viable option for patients with degenerated bioprosthetic valves at high risk for redo surgery. We report a case of a patient who had degenerated mitral and tricuspid bioprosthesis causing severe tricuspid and mitral regurgitation. We performed simultaneous mitral and tricuspid valve-in-valve replacement via a transfemoral approach. Although the data on performing both valve-in-valve procedures are limited, this case demonstrated that these procedures can be safely done as a single procedure.
