Demonstrates the feasibility of percutaneous transvenous antegrade mitral valve-in-valve implantation using a Melody valve in a high-surgical-risk patient.
May offer transvenous mitral ViV access in select high-risk patients; hypothesis-generating and requires prospective validation.
We report a case of transcatheter valve-in-valve therapy performed on an 85-year-old man with severe mitral bioprosthetic valve dysfunction. He was a high risk candidate for conventional surgery and he underwent placement of the Melody transcatheter heart valve into the mitral bioprosthesis via the right femoral vein.
