摘　　要：4例风湿性心脏病二尖瓣狭窄患者行经皮气囊二尖瓣成形术(PBMV),均获成功,左心房平均压自术前22.0±3.3降为8.5±2.6mmHg(P<0.001),二尖瓣压力阶差自17.0±1.8降为6·5±2.1mmHg(P<0.001),肺动脉收缩压自32.8±9.1降为15±4.8mmHg(P<0.05),二尖瓣口面积自1.25±0.04扩大至2.34±0.19cm^2(P<0.001),随访1个月至2个月患者心功能及二尖瓣口面积持续改善,左心房前后径自术前53.3±2.4mm 缩小至43.8±3.6mm(P<0.001)。PBMV 无须开胸手术,痛苦少,术后康复快,短期或长期疗效与闭式二尖瓣分离术相似,基本上可替代闭式二尖瓣分离术。Four patients with rheumatic mitral stenosis underwent percutaneous balloon mi-tral valvuloplasty with the result of significant improvement PBMV.The mean left atrial pressure decreased from 22.0±3.3 to 8.5±2.6mmHg(P<0.001);mitral valve area increased from 1.25±0.04 to 2.34±0.19cm^2(P<0.001);mitral valvegradient decreased from 17.0±1.8 to 6.6±2.1mmHg(P<0.001);pulmonary systolic pre-ssure decreased from 32.8±9.1 to 15±4.8mmHg(P<0.05).After 1 to 2 months offollow-up examinations showed that the cardiac function improvement and the increasedmitral orifice area were well maintained.Left atrial anteroposterior diameterdecreased from 53.3±2.4mm to 43.8±3.6mm(P<0.001).PBMV avoids thoracotomy,minimizing pain with short hospital stay and recoveryperiod.The short and long term results showed no difference between PBMV andclosed mitral commissurotomy PBMV is an attractive alternative to closed mitralcommissurotomy.
