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

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.
