Transcatheter valve-in-valve implantation for early prosthetic valve degeneration in aortic and mitral positions.

Recently, transcatheter valve-in-valve implantation has emerged as a new alternative to surgical reoperation for degenerated bioprosthetic valves, either in the aortic or mitral position. The early experience and outcome of this strategy appears promising in highly selected patient groups. Here we report a case of early structural valve degeneration in the aortic and mitral position in a patient with chronic hemodialysis successfully treated with transthoracic transcatheter valve-in-valve implantation.
