[Percutaneous transluminal pulmonary valvuloplasty. Results in 34 cases].
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.
