The single-suture neochorda-folding plasty technique is a modification of existing mitral valve repair techniques. In the authors' experience, its simplicity, reliability, and versatility make it a useful technique for mitral valve repair, especially when a minimally invasive approach is used.

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.

To evaluate the change in valvular morphology and occurence and severity of mitral regurgitation produced by PMV, 45 patients(33 women and 12 men,mean age 38+/-10 years) were studied using two-dimensional(2-D) and Doppler echocaediography before and 1-2 days after this procedure. Mitral valve area after PMV increased in all patients, from 0.9+/-0.2 to 1.8+/-0.4cm2(P<0.0001). In valve area estimation, the correlation between Gorlin`s method and 2-Dechocardiography was better(r=0.61, p<0.0001) than that between Gorlin`s method and Doppler pressure halftime(r=0.38, P<0.01) before valvuloplasty, but after the procedure Gorlin`s and 2-D image valve area correlated less well(r=0.33, P<0.05) than Gorlin`s-Doppler pressure halftime correlation(r=0.46, P<0.002). Before PMV, 37 patients had no mitral regurgutation, 7 had grade 1 and 1 had grade 2 mitral regurgutation. After PMV, new mitral regurgutation occurred in 14 patients, increased in severity in 5 patients and so mitral regurgutation newly developed or increased in severity in 19(42%) patients. There were no differences between the patients with and those without an increase in mitral regurgutation after PMV, in age, sex, caediac rhythm, initial mitral valve area, increase in mitral valve area and fluoroscopic calcification. However, morphologic characteristics especially mobility(P<0.01) and thickening(P<0.05) of mitral leaflets were better pressured, and EBDA/BSA(effective balloon dilating area/body surface area) was significantly smaller(P<0.02) in patients without an increase in mitral regurgutation. Thus, an increase in mitral regurgutation after PMV might be related to the features of valve morphology especially and thickand EBDA/BSA.
