title: A Hybrid Double Access for Transcatheter Mitral Valve-In-Valve Implantation.
abstract: We present a case of hybrid mitral valve-in valve implantation. The planned transapical approach failed due to the inability to cross the degenerated stenotic mitral bioprosthesis. An alternative strategy was performed: first, an anterograde crossing of mitral stenosis, and then, a guidewire externalization through the apex by using a snare. To our knowledge, this is the first described case of double approach mitral valve-in valve implantation.
