摘　　要：Transcatheter mitral valve replacement(TMVR)has become an alternative to surgical mitral valve replacement for the treatment of patients with severe mitral insufficiency(MI)who are at very high or prohibitive surgical risk.[1]Because of impaired left ventricular dysfunction and previous cardiac surgery,some aged patients with degenerated bioprosthetic mitral valve and mitral regurgitation were refused to redo surgery.[2]Increasing demand are required for minimally invasive treatment of these patients.Hundreds of patients worldwide have been treated with a transcatheter mitral valve-in-ring or valve-in-valve procedure using transcatheter aortic valve.[3]However,rare case of transcatheter mitral valve-in-valve/ring replacement using transcatheter mitral valve system was reported.Here,we reported a successfully case of transcatheter mitral“valve-in-valve”replacement for the treatment of bioprosthetic mitral valve degeneration and severe regurgitation with domestic Mithos^TM valve.
