巨大左心房患者经皮球囊二尖瓣成形术20例

20 Cases Report on Percutaneous Balloon Mitral Valvuloplasty with Very Large Left Atrial Dimensim

目的 探讨经皮球囊二尖瓣成形术 (PBMV)治疗风湿性心脏病二尖瓣狭窄伴巨大左心房患者的疗效。方法 在球囊直径选择、房间隙穿刺定位方法及球囊扩张操作等方面进行了改良。结果 2 0例病人手术全部成功 ,二尖瓣面积由 (0 .79±2 .9) cm2 增至 (1 .82± 0 .2 8) cm2 (P<0 .0 1 ) ,左房平均压由 (3 0 .7± 5 .1 ) mm Hg降至 (1 1 .4± 3 .7) mm Hg(P<0 .0 1 ) ,心功能明显改善。结论 PBMV治疗风湿性二尖瓣狭窄伴巨大左心房患者成功率高、疗效较好 ,在 PBMV术操作熟练后 。

Objective To evaluate the effect of percutaneous balloon mitral valvuloplasty(PBMV)on rehumatic mitral stenosis with very large left atrial dimensim Methods PBMV was performed on 20 patients, some operation procedure was changed Results After PBMV, the area of mitral valve increased from(0.79±2.9)cm 2 to(1.82±0.28)cm 2( P <0.01), the pressure of left atrium decreased from(30.7±5.1)mmHg to(11.4±3.7)mmHg( P <0.01) Conclusion PBMV is a safe and effective procedure for rehumatic mitral stenosis with very large left atrial dimensim
