摘要 目的总结二尖瓣脱垂(mitral valve prolapse,MVP)合并感染性心内膜炎(infectous endocarditis,IE)的临床特点、手术时机和手术前后超声心动图的特点。方法2000年6月至2007年12月我科共收治原发性MVP合并IE患者45例,术前心功能分级(NYHA)Ⅱ级15例,Ⅲ级21例,Ⅳ级9例。术前血培养阳性率为40%,最常见的为草绿色链球菌(38.9%)。术前超声心动图检查发现腱索断裂3例,急性左心功能衰竭9例,有脑血管意外6例。术中根据瓣膜质量和损伤情况,行二尖瓣成形术5例,二尖瓣置换术35例;同期行主动脉瓣置换术6例,三尖瓣成形术19例,冠状动脉旁路移植术1例。结果术前死亡5例,3例死于脑血管意外,2例死于多器官功能衰竭;术后早期死亡1例,死于肾功能衰竭;长期生存39例,术后随访6个月~8年(平均2.7年),无晚期死亡,超声心动图复查未见心内膜炎复发及瓣周漏。结论MVP合并IE的临床特点为起病隐匿,心力衰竭、体循环栓塞(尤其脑栓塞)等并发症的发生率较高。对中至重度关闭不全的MVP合并IE患者应早期治疗。
