Insights
Percutaneous balloon valvuloplasty effectively treated moderate to severe pulmonary valvular stenosis in 45 pediatric and adult patients. The procedure significantly reduced right ventricular pressure and the right ventricular/pulmonary artery gradient.

Abstract:
Forty five patients with moderate or severe pulmonary valvular stenosis had been treated by percutaneous balloon valvuloplasty. The age of these patients varied between 55 days and 24 years. Nine patients (group 1) had a right ventricular/pulmonary artery gradient (RV/PA) between 25 and 50 mmHg, thirty six patients (group 2) had a RV/PA gradient superior to 50 mmHg. Fourty nine dilatations had been practised. The right ventricular pressure failed from 106.31 +/- 46.03 mmHg to 61.11 +/- 32.62 mmHg. The RV/PA gradient passed from 86.02 +/- 45.64 mmHg to 39.58 +/- 32.16 mmHg and the ratio of right ventricular pressure/systemic pressure passed from 0.98 +/- 0.44 to 0.49 +/- 0.23. The difficulties, failures, and the results are discussed together with predilectory factors.
