Abstract:
BACKGROUND: Mitral valve repair has been suggested to provide better postoperative outcome than valve replacement for mitral regurgita tion. MATERIAL AND METHOD: From Janu ary 1996 to May 2000, 87 patients had mitral valve repair(59 patients) or replac ement(28 patients) for mitral regurgitation. RESULT: The two groups were si milar in age, sex, and functional class. The cause of mitral regurgitation in th e repair group was degenerative in 45 patients, rheumatic in 12 patients, endoca rditis in 1, and ischemic in 1, and in the replacement group was degenerative in 12 patients, rheumatic in 11 patients, endocarditis in 4 and traumatic in 1 pat ient. A Carpentier ring was used in 51 patients and the most common size was 30 mm. The aortic cross-clamp time was 88.3+/-24.7 minutes in the repair group and 7 0.3+/-23.8 minutes in the replacement group(p<0.05), and total pump time was 13 9.6+/-30.5 minutes and 110.4+/-34.3 minutes(p<0.05) respectively. There was no hos pital death in both groups. Four-year actuarial survival was 97.9% for the repai r group and 100% for the replacement group(p = not significant). Postoperative c ardiothoracic ratio and ejection fraction decreased, and postoperative functiona l class improved in both groups(p = not significant). CONCLUSION: Mitral valve repai r for patients with mitral regurgitation can be performed with the satisfactory results as valve replacement.
