经皮球囊二尖瓣分离术治疗二尖瓣狭窄

Treatment of Mitral Stenosis With Percutaneous Balloon Catheter Mitral Commissurotomy

经皮球囊导管二尖瓣分离术（ＰＢＭＣ）治疗风湿性二尖瓣狭窄１０例，其中男３例，女７例，平均年龄３８．５岁（２４～６３岁），均用单球囊法，９例成功（９０％）。术后血液动力学及二维超声心动图均有明显改善，平均左房压由２．４１１±０．８０７ｋＰａ降到０．７１５±０．２９６ｋＰａ（Ｐ＜０．００１）．左房内径降到３７±３．１３ｍｍ（Ｐ＜０．０２），二尖瓣口面积由１．３±０．３５ｃｍ２增大到２．１６±０．３９ｃｍ２（Ｐ＜０．０２），无１例死亡。本文讨论了ＰＢＭＣ近期及远期治疗效果、手术操作及主要并发症。

Percutaneous balloon catheter mitral commissurotomy (PBMC)was performed in 10 patients(m=3,f=7,with age 24～63 years, mean age 38. 5 years)with rheumatic mitral stenosis by single ballon catheter and were succesful in 9 patients(90%).After PBMC,there was a significant improvement in hemodynamics and the two-dimensional echocardiography(2DE),mean left atrial pressure(18.13± 6.07mmHg to 5. 38±2.23mmHg,P<0. 001),left atrial diameter(37±3. 13,P<0.02),mitral valve area(1.3±0. 35cm2 to 2. 16±0. 39cm2 p<0.01).No death was occurred.In addition, the short term and remote effects, operational manipulations and main complications of PBMC were discussed.
