Purpose : Although repair of the posterior leaflet has been traditionally performed by techniques including leaflet resection, it can be challenging in restoration of the coaptation surface. The purpose of this study is to evaluate the early outcomes of nonresectional folding mitral valvuloplasty for posterior mitral leaflet prolapse.
Methods : Between November 2011 and April 2017, 50 consecutive patients diagnosed with posterior mitral leaflet prolapse underwent nonresectional folding mitral valvuloplasty. Mean age was 69.9±14.3 years. In addition to folding valvuloplasty, ring annuloplasty was performed in all patients, and maze operation was performed concomitantly in 11 patients for atrial fibrillation. Postoperative echocardiography was performed in all patients, and medical records were reviewed retrospectively.
Results : Folding mitral valvuloplasty was performed mainly for the P2 segment in 32 patients (64%), for the P3 in 12 patients (24%), for the P2 and P3 in 2 patients (4%), and for the P1 segment in 3 patients (6%). There was no early (within 30 days postoperatively) mortality. No patients required reoperation of the folding mitral valvuloplasty. On follow-up (median 34 months, range 4 to 60), echocardiography demonstrated that only 1 patient (2%, out of 50) experienced aggravation of the initial degree of mitral regurgitation.
Conclusion : Our results demonstrate that nonresectional folding mitral valvuloplasty may be a simple alternative technique for isolated posterior mitral leaflet prolapse, compared to the complexity and irreversibility of the classic resectional repair consisting of triangular or quadrangular resection of prolapsed posterior segment with sliding valvuloplasty. Further studies should be performed to confirm the durability of this folding repair.
