Transcatheter mitral valve replacement for degenerated mitral bioprostheses: a systematic review

Transcatheter MVIV is an effective treatment for structural degeneration of biologic mitral valve replacement with low complication rates and favorable one-year outcomes. Accordingly, MVIV should be considered as a reasonable alternative to re-do surgical mitral valve replacement in high risk patients with comorbidities. Further study of long-term outcomes of this treatment is needed.
