Surgical repair of the prolapsing anterior leaflet with chordal shortening.
The purpose of this study was to review the results of mitral valve repair for prolapse of the anterior repaired with chordal shortening or shortening of the papillary muscle. Sixty three patients operated from June 1988 through June 2003, form the cohort of this study. The etiology was degenerative disease in 30 patients (47%) and rheumatic disease in 23 (37%). All patients survived the operation. Predischarge echocardiography showed no or trivial regurgitation in 61 patients (97%). Mean follow-up was 6.57 +/- 0.65 years. Twenty patients died during the follow-up for an actuarial survival of 62% at 14 years. Five patients required reoperation on the mitral valve; 88% of the patients were free from reoperation at 14 years. In conclusion, shortening plasty of the subvalvular apparatus provides good and stable results after repair of anterior leaflet prolapse.
