Transcatheter implantation of aortic valve prostheses into degenerated mitral valve bioprostheses and failed annuloplasty rings: outcomes according to access route and Mitral Valve Academic Research Consortium (WPC) criteria

摘要

Aims: The study sought to assess outcomes of transcatheter mitral valve-in-valve implantation (TMVIV) for degenerated bioprostheses and transcatheter mitral valve-in-ring implantation (TMVIR) for failed annuloplasty rings according to access route and the Mitral Valve Academic Research Consortium (MVARC) criteria.
