摘要 目的 :总结保留整个二尖瓣腱索和乳头肌行二尖瓣瓣膜置换手术 (MVR)的经验。方法 :回顾分析 2 0 0 1年 1月至 2 0 0 4年 6月我科完成的 4 3例保留整个二尖瓣和瓣下结构的瓣膜置换手术患者的临床资料。其中男性 14例 ,女性 2 9例 ,平均年龄 (49± 13)岁 ;风湿性心脏病 36例 ,瓣膜退行性病变 4例 ,二尖瓣前瓣腱索断裂 3例 ;单纯二尖瓣关闭不全 11例 ,二尖瓣关闭不全为主伴狭窄 2 3例 ,二尖瓣狭窄为主伴关闭不全 9例 ;NYHA心功能Ⅱ级 7例 ,Ⅲ级 2 7例 ,Ⅳ级 9例 ;超声心动图示左心室舒张末直径平均 (5 5± 5. 5 )mm ,左心室射血分数 (LVEF)平均 0 .4 6± 0 . 0 6 ;5例有脑栓塞史 ,4例有糖尿病史 ;手术均在全麻中低温体外循环下进行 ;采用Miller法保留后瓣及瓣下结构、改良的Miki法保留前瓣及瓣下结构 ;均置换机械瓣 ,其中 19例用国产C L短柱倾碟瓣 ,2 4例用CarboMedics双叶瓣 ;17例同时行主动脉瓣置换术 ,其中 2例行窄小主动脉瓣环拓宽术 ;1例同时行主动脉瓣、三尖瓣置换术 ;35例合并三尖瓣返流者同时行三尖瓣成形术 ;1例同时行COX迷宫术 ;5例同时行左心房血栓清除术 ;4例巨大左心房同时行左心房折叠术 ;心肌阻断时间平均 (10. 9± 36 )min ,体外循环时间平均 (16 7± 4 2 )min。结果 :术后早期死亡
