BACKGROUND AND AIM OF THE STUDY: Mitral valve repair is the procedure of choice for severe degenerative mitral regurgitation (MR). The objective of this study was to review prospectively gathered echocardiographic and clinical results with mitral valve repair for degenerative disease. METHODS: Between May 1995 and July 2004, 403 patients underwent mitral valve repair for degenerative disease (mean age 63 +/- 12 years, 72% males). Concomitant procedures included CABG (29%), radiofrequency left-sided maze procedure (8%), aortic valve replacement (6%), and tricuspid valve repair (4%). RESULTS: Thirty-day mortality was 0.4% for patients with isolated mitral valve repair and 5.1% for patients with mitral valve repair and concomitant procedure (p = 0.003). Five-year survival was higher for isolated mitral valve repair compared to mitral valve repair with a combined procedure (92 +/- 2% vs. 76 +/- 5%; p < 0.001). Pulmonary artery pressure and left atrial and left ventricular end-diastolic diameters were significantly improved following mitral valve repair (all p <or= 0.005) and this was sustained afterward. The freedom from severe (3+ or 4+) and moderate-severe (2+, 3+, or 4+) MR was 95% and 77% at 5 years, respectively, whereas the freedom from reoperation was 96 +/- 1% at 5 years. Significant predictors of moderate-severe MR recurrence were cardiac dilatation, anterior leaflet prolapse, and concomitant procedure, whereas mitral valve disease amenable to posterior leaflet resection had a lower risk of MR recurrence. CONCLUSIONS: Excellent clinical outcomes can be obtained using standard techniques of mitral valve repair of the degenerative valve. MR recurrence is low but nonnegligible, emphasizing the necessity for long-term postoperative echocardiographic follow-up in these patients. |
