摘要 目的探讨改良自制心包成形条在二尖瓣成形术(MVP)中的应用及其效果。方法回顾性分析该院2013年1月至2016年6月收治的42例二尖瓣关闭不全(MI)患者的临床资料,均在体外循环下修复二尖瓣瓣叶及瓣下结构,采用经戊二醛固定后的自体心包条进行折叠,并包裹涤纶条,自制成柔性环环缩二尖瓣后瓣环。术后1、3、6、12个月定期门诊随访。比较患者术前、出院前及术后1个月左心房内径(LA)、左心室舒张末期直径(LVDD)及左心室射血分数(LVEF)。随访6~36个月,记录患者心功能分级。结果本组患者体外循环时间为(97.80±38.40)min,主动脉阻断时间为(60.70±25.80)min。术后经食道心脏超声检查显示,无反流31例,微量反流7例,轻度反流4例。与术前比较,出院前及术后3个月LA、LVDD均明显缩小(P<0.05)。术后1年40例患者获得随访,随访期间无死亡病例,因心功能衰竭入院调整1例;纽约心脏病协会(NYHA)心功能分级Ⅰ级37例,Ⅱ级2例,Ⅲ级1例。结论 MVP中应用改良自制心包成形条成形对各种原因导致MI成形技术简单,费用低廉,手术安全、有效,近期效果好。
