摘要(Abstract)：
目的 探讨二尖瓣狭窄 (MS)并中度反流 (MR)患者经皮二尖瓣球囊扩张术 (PBMV)近远期疗效。方法 采用Inoue单球囊对 42例风心病二尖瓣狭窄并中度反流患者行PAMV治疗。结果 二尖瓣口面积由 (0 92± 0 2 2 )cm2 增至 (1 94± 0 2 5 )cm2 (P <0 0 1) ;二尖瓣跨瓣压差由 (2 7± 1 0 1)kPa降至 (1 0 2± 0 5 6 )kPa(P <0 0 1) ;心功能由 (2 6 1± 0 2 2 )级改善至 (1 42± 0 46 )级 (P <0 0 1) ;左室最大前后径无明显变化 (P >0 0 5 )。 2例患者二尖瓣反流较术前加重。随访 37例患者 (18± 4)个月 ,二尖瓣口面积、左室最大前后径及心功能与术后比较 ,均无明显变化 (P >0 0 5 )。结论 掌握好病例选择 ,严格把握球囊扩张尺度 ,风心病二尖瓣狭窄并中度反流患者PBMV近、远期疗效满意
