We present 11 cases of pulmonary valve stenosis who underwent percutaneous dilatation angioplasty. Patients were between 2 and 15 years old (mean age = 6.5 yrs) and all of them except 3 had moderate or severe degree of valve stenosis. Pulmonary anulus diameter ranged between 11 and 23 mm. at ECHO and between 10 and 21 mm. at angio. The catheter was chosen to be 20-40% larger than pulmonary anulus. The mean pressure gradient between RV and PA was 65 mmHg. before dilatation and 21 mmHg. after the procedure. The procedures were without complications, except one in which we observed an intermittent idioventricular rhythm for few days after the procedure. Percutaneous dilatation angioplasty has to be considered the treatment of choice for pulmonary valve stenosis.
我们报告了11例接受经皮扩张血管成形术治疗的肺动脉瓣狭窄病例。患者年龄在2至15岁之间（平均年龄 = 6.5岁），除3例患者外，其余患者均为中度或重度瓣膜狭窄。超声心动图显示肺动脉环直径在11至23毫米之间，血管造影显示在10至21毫米之间。选择的导管比肺动脉环大20%至40%。扩张前右心室和肺动脉之间的平均压力梯度为65毫米汞柱，术后为21毫米汞柱。除1例患者在术后几天出现间歇性室性心律外，手术均无并发症。经皮扩张血管成形术应被视为肺动脉瓣狭窄的首选治疗方法。
