Multicenter StudyPercutaneous Transvenous Transseptal Transcatheter Valve Implantation in Failed Bioprosthetic Mitral Valves, Ring Annuloplasty, and Severe Mitral Annular Calcification.
This study sought to examine the feasibility, safety, and intermediate-term outcomes in patients undergoing percutaneous transvenous transcatheter mitral valve implantation in failed bioprosthesis, ring annuloplasty, and calcific mitral stenosis. ⋯ Transfemoral percutaneous transvenous mitral valve implantation in high-risk patients with degenerated bioprosthesis is safe, effective, and associated with rapid improvement in hemodynamics, short length of stays, and improved functional status. Percutaneous mitral valve implantation in patients with failed annuloplasty rings and severe MAC is a promising therapy with significant short-term morbidity and mortality that requires further study.
