Two case reports of transcatheter valve-in-valve implantation of Sapien 3 and MyVal in degenerated biological tricuspid prosthesis valves.

ABSTRACT

Background: Patients with severe tricuspid valve stenosis or dysfunction following degeneration of biological valve prosthesis in tricuspid position are complex, have substantial comorbidity, and very high surgical risk. Case summary: We report two cases with transcatheter tricuspid valve-in-valve implantation in patients with degenerated tricuspid bioprosthesis with transfemoral and transjugular access with Sapien 3 valve and MyVal, respectively. Discussion: In patients with high surgical risk, transcatheter tricuspid valve implantation is a good alternative. Careful consideration of optimal access site, device size, and delivery system is paramount. This case report demonstrates technically feasible and safe transcatheter valve-in-valve implantantion in tricuspid position and highlights the importance of meticulous procedure planning.
