Surgical repair of complex mitral valve regurgitation with the comprehensive application of multiple techniques / 中华胸心血管外科杂志

ABSTRACT

Objective To evaluate the clinical application and midterm result of mitral valve repair with multiple techniques for patients with complex mitral valve regurgitation. Methods From January, 2000 to July, 2006, 34 patients with complex mitral regurgitation, including 24 males and 10 females, aged 23 - 65 years [ average (42.8 ± 11.7) years ], comprised the study group. The data of the cardiac function (NYHA/EF), the diameter of left ventricular, left atria and the degree of mitral regurgitation were analyzed before and after operation. Results There was no mortality or major morbidity or reoporatien. Patients were followed up from 1 to 54 months [ average (31.2 ± 19.4) months]. The degree of mitral valve regurgitation decreased significantly after operation. The mean degree of pre-operatien mitral regurgitation was 3.62 ± 0.49, and follow-up degree was 1.18 ± 0.99 ( P ＜ 0.05) respectively.The diameters of left ventricular and left atria reduced. The postoperative cardiac function improved apparently. EF increased from 0.55 ± 0.11 preoperatively to 0.57 ± 0.10 postoperatively ( P = 0.06). Conclusion The comprehensive application of multiple techniques in repairing complex mitral valve regurgitation may be effective, and with a satisfying midterm results.
