[Percutaneous balloon dilatation of pulmonary valve stenosis].
Balloon valvuloplasty was carried out on five children with isolated valvular pulmonary stenosis. One child had a residual stenosis following a Brock's transventricular valvotomy. The systolic gradient between the right ventricle and the pulmonary artery fell from 60.4 +/- 18.7 mmHg to 21.8 +/- 12.0 mmHg. Right ventricular pressure fell from 76.2 +/- 20.7 mmHg to 43.0 +/- 16.4 mmHg. Percutaneous balloon valvuloplasty has proved to be an effective method for the treatment of isolated valvular pulmonary stenosis.
