Long-Term Results (≤18 Years) of the Edge-to-Edge Mitral Valve Repair Without Annuloplasty in Degenerative Mitral Regurgitation: Implications for the Percutaneous Approach.

In this retrospective review, the authors evaluate the long-term outcome of 61 patients undergoing edge-to-edge mitral valve repair without annuloplasty ring for degenerative mitral regurgitation (MR). The reasons for not performing annuloplasty were either severe annular calcification or absence of significant annular dilatation. Follow up was 100%. Overall survival at 12 years was 51±7%, and freedom from MR ≥3+ was 43±7.6%. Twenty-one patients required reoperation during the follow up period. These findings lead the authors to conclude that in degenerative MR, the overall long-term results of the surgical edge-to edge technique without annuloplasty are not satisfactory. The authors underscore the relevance this may have in transcatheter mitral valve repair procedures.
