二尖瓣脱垂的外科治疗

报道５７例二尖瓣脱垂（ＭＶＰ０不同术式的外科治疗效果。手术随机分为３组；传统的二尖瓣成形组，Ｇｏｒｅ－Ｔｅｘ线人工腱索替换组和瓣膜置换组。结果显示，Ⅱ组和Ⅲ组术后每搏二尖瓣返流量明显少于Ⅰ组。各组术后长期随访机能状况均明显改善。ＭＶＰ的外科治疗应首选二尖瓣成形；而Ｇｏｒｅ－Ｔｅｘ线人工腱索替换和人造瓣环盛开有方法安全可靠，其效果优于传统的腱索成形，并可避免瓣膜置换术后长期抗凝的并发症。

Surgical treatment for mitral valve prolapse]

OBJECTIVE: To determine the excellent operative procedure to treat mitral valve prolapse (MVP). METHODS: Fifty seven patients with MVP were divided into three groups: Group I received traditional chordal reconstruction; Group II underwent chordal replacement using expanded polytetrafluorethylene(e-PTFE) sutures and artificial ring valvuloplasty reconstruction; Group III submitted mitral valve replacement. RESULTS: Mitral regurgitation volume was reduced significantly in Group II [(1.3 +/- 3.8) ml] and Group III [(1.2 +/- 3.4) ml] than that in Group I [(4.7 +/- 7.7) ml] (P < 0.05). CONCLUSION: The utilization of e-PTFE sutures as artificial chordae and artificial ring valvuloplasty for MVP is a more reliable and safe procedure than traditional mitral valve reconstruction, and can avoid the complications of long term anticoagulant therapy after mechanical valve replacement.
