Polish Transcatheter Transfemoral Mitral Valve-in-Valve Implantation (Mitral ViV) Registry

Transcatheter transfemoral mitral valve-in-valve implantation is an alternative for surgery redo in high-surgical-risk patients with bioprosthetic valve failure. The procedure is performed via femoral vein access. By the transseptal puncture (in the postero-inferior part of the interatrial septum) and balloon septostomy, the bioprosthetic valve is introduced through the degenerative valve into the left ventricle. The valve is expanded in the mitral position during rapid ventricle pacing.
