二尖瓣腱索断裂是常见的退行性二尖瓣病变,如果行瓣膜置换,需长期抗凝且左心室功能受损。而二尖瓣成形术有利于保护左室功能[1],降低术后抗凝并发症[2],已成为退行性二尖瓣病变患者首选手术方式[3]。人工腱索移植术是二尖瓣腱索断裂常见术式,可有效保留瓣叶开放面积。但该术式技术难度较大,各项要求较高,国内开展较少,尚处于起步阶段[4]。2010年1月—2015年
Mitral chordal tendon rupture is a common degenerative mitral valve disease, if the valve replacement, need long-term anticoagulation and impaired left ventricular function. Mitral valvuloplasty is good for the protection of left ventricular function [1], reducing the postoperative anticoagulant complications [2], and has become the preferred surgical method in patients with degenerative mitral valve disease [3]. Artificial chordae tendinotomy is a common operation of mitral chordae tendinea rupture, which can effectively retain the open area of valve leaflets. However, the surgical technique is more difficult, the requirements are higher, and there are fewer domestic ones. It is still in its infancy [4]. January 2010 - 2015
