Percutaneous transluminal valvuloplasty with catheter-balloon were performed in thirty-four patients with pulmonary valve stenosis, aged 2 to 11 years (mean = 4.8 +/- 2.4 years). It was a slight stenosis in 24 cases (70.5%) and severe in 10 cases (29.5%). In three of them it was a dysplastic valve. We achieved good results, since right ventricle systolic pressure, decreased from mean = 67 +/- 18 mmHg to mean = 23 +/- 12 mmHg (p less than 0.0001). In the three cases with dysplastic valve, results were rather poor. Procedure was well stood-up and there were no serious complication. We conclude that at the present time valvuloplasty its the elective treatment in pulmonary stenosis in childhood except in cases with dysplastic valve.
对34例年龄在2至11岁（平均4.8±2.4岁）的肺动脉瓣狭窄患者进行了经皮导管球囊瓣膜成形术。其中24例（70.5%）为轻度狭窄，10例（29.5%）为重度狭窄。其中3例为发育异常瓣膜。我们取得了良好的效果，右心室收缩压从平均67±18 mmHg降至平均23±12 mmHg（p<0.0001）。在3例发育异常瓣膜的病例中，效果较差。手术耐受性良好，无严重并发症。我们得出结论，目前瓣膜成形术是儿童肺动脉狭窄的选择性治疗方法，但发育异常瓣膜的病例除外。
