ABSTRACT
Leaflet resection for posterior leaflet prolapse has been a standard repair procedure with good longterm durability. The aim of this study was to review our experience of mitral valve repair, in which resection of the anterior and/or posterior leaflets was performed. Between October 1991 and December 2010, 172 patients with degenerative mitral valve regurgitation underwent mitral valve reconstruction,including 98 patients with the posterior leaflet prolapse, 47 patients with the anterior leaflet prolapse, 17 patients with both leaflets and 10 patients with the commissure prolapse. Most patients in this study were supposed to be caused by fibroelastic deficiency and we have not experienced systolic anterior motion after repair. The mean follow-up period was 8.7 ± 5.5 years. The freedom from reoperation rates at 15 years in 88.7 ± 5.3% of the anterior leaflet procedure, 96.6 ± 2.5% of the posterior leaflet, and 100% of both leaflets. The results of resection of a diseased prolapsed mitral leaflet have been promising so far. However, reoperation was required in 7 patients (4.1%) and reoperation rate was higher in patients with anterior prolapse and longer follow-up will evaluate precisely be benefit.
