摘要 目的探讨自体心包成形条在二尖瓣成形术中的应用效果。方法选择二尖瓣关闭不全患者112例,均在体外循环下修复二尖瓣瓣叶及瓣下结构,采用自体心包条环缩瓣环。停体外循环,经食道心脏超声检查评估二尖瓣成形效果。比较患者术前、出院前及术后6个月左心房内径、左心室舒张末直径及左心室射血分数。随访12~46个月,记录患者心功能分级。结果本组体外循环时间(125.4±31.3)min,主动脉阻断时间(75.6±22.7)min,围术期死亡2例。术中经食道心脏超声检查示,无反流42例,微量反流40例,轻度反流20例。与术前比较,出院前及术后6个月左心房内径、左心室舒张末期内径明显降低,左心室射血分数明显升高(P均<0.05)。术后102例获得随访,随访期间死亡2例,行二尖瓣置换术2例;NYHA心功能分级Ⅰ级85例,Ⅱ级13例。结论二尖瓣成形术中应用自体心包成形条成形安全、有效。
