Late echocardiographic and clinical outcomes after mitral valve repair for XXXX .

@entity1 @entity339 @entity384 @entity886 @entity179
BACKGROUND AND AIM OF THE STUDY: Mitral valve repair is the procedure of choice for severe @entity339 ( @entity339 ). The objective of this study was to review prospectively gathered echocardiographic and clinical results with mitral valve repair for @entity179 . METHODS: Between May 1995 and July 2004, 403 @entity1 underwent mitral valve repair for @entity179 (mean age 63 +/- 12 years, 72% males). Concomitant procedures included CABG (29%), radiofrequency left-sided maze procedure (8%), @entity886 (6%), and tricuspid valve repair (4%). RESULTS: Thirty-day mortality was 0.4% for @entity1 with isolated mitral valve repair and 5.1% for @entity1 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+) @entity339 was 95% and 77% at 5 years, respectively, whereas the freedom from reoperation was 96 +/- 1% at 5 years. Significant predictors of moderate-severe @entity339 recurrence were @entity384 , anterior leaflet prolapse, and concomitant procedure, whereas @entity339 amenable to posterior leaflet resection had a lower risk of @entity339 recurrence. CONCLUSIONS: Excellent clinical outcomes can be obtained using standard techniques of mitral valve repair of the degenerative valve. @entity339 recurrence is low but nonnegligible, emphasizing the necessity for long-term postoperative echocardiographic follow-up in these @entity1 .
