摘要 35例合并巨大左心室瓣膜病患者,于体外循环下采用二尖瓣置换术。其中11例术中保留全部二尖瓣(保留全瓣组),24例仅保留后瓣及其腱索、切除前瓣及其腱索(保留后瓣组)。术后1个月采用超声心动图测量两组患者手术前后左心室舒张末容积指数(LVEDVI)、收缩末期容积指数(LVESVI)、左心室舒张末直径(LVEDD)、收缩末期直径(LVESD)、左心室射血分数(EF)、短轴缩短率(FS)、每搏指数(SVI)。结果保留全瓣组手术后无早期死亡病例,发生严重心律失常1例;保留后瓣组手术后早期死亡1例,发生严重心律失常和低心室排血量综合征各1例。两组术后LVEDVI、LVESVI、LVEDD、LVESD均较术前明显缩小(P均<0.01),保留全瓣组LVEDVI、LVEDD较保留后瓣组低(P<0.05);EF、FS和SVI两组均优于术前(P均<0.01)。认为合并巨大左心室的瓣膜病患者行二尖瓣置换术时宜保留全部二尖瓣结构。
