二尖瓣人工瓣环成形术18例

目的回顾性分析１８例二尖瓣人工瓣环成形术的疗效。方法风湿性病变３例，退行性变１１例，先天性病变４例。重度关闭不全１６例，中度关闭不全２例。根据二尖瓣病理改变对瓣叶和瓣下结构做针对性瓣膜成形术后，均植入人工瓣环。１０例在经食道超声心动图监测下行成形术。结果成形中术后二尖瓣无返流６例，轻度返流９例，中度返流１例。２例改行二尖瓣置换术。随访７个月至６年７个月，平均３．６年，心功能均有显改善。结论对于

Prosthetic ring for mitral annuloplasty (Report of 18 cases)

Objective This article is to review the experience of prosthetic mitral annuloplasty. Methods The cause of valvular incompetence was found to be rheumatic in 3 cases, myxomatous degeneration in 11 and congenital in 4. The mitral valve incompetence was grad-ed as severe in 16 cases and moderate in 2. All patients underwent mitral annuloplasty using prosthetic mitral ring. 10 patients underwent mitral annuloplasty in use of intraoperative transeophaged echocardiography. Results The mitral valve incompetence was graded as no incompe-tence in 6 cases, slight in 9 and moderate in 1 after surgery. Two patients underwent mitral valve replacement. Patients were followed up for 7 months to 6 yeras tions 7 months (average 3.6 years). Their cardiac functions were improved. Conclusion The late efficacy of mitral annuloplasty using prosthetic ring is satisfactory.
