Surgical mitral valve repair for degenerative mitral regurgitation (DMR) is effective for all prolapse complexities with or without annular dilation, a goal not yet achievable with existing transfemoral solutions.
A transfemoral mitral repair device that provides both chordal replacement (for leaflet prolapse) and annuloplasty (for annular dilation) could challenge the dominance of surgical repair. If the concept is feasible for all valve segments, then for such a device the ...
