Abstract
Balloon valvuloplasty has become the treatment of choice in pulmonary valvular stenosis. The objective of this report is to review the experience of this procedure in children at the Department of Pediatrics, Ramathibodi Hospital in the past 4 years (1991 - 1994) with at least one year follow-up. During the study period, 19 children aged 2.1 - 14.3 years (mean 5.11 years) with the diagnosis of pulmonary valvular stenosis had successful pulmonary balloon valvuloplasty at this institution. The immediate peak systolic pressure gradient across the pulmonary valve by cardiac catheterization decreased from 92.05 ±46.92 to 34.26 ±25.30 mmHg, by Doppler from 78.58 ± 26.55 to 34.83 ±15.60 mmHg. Peak pressure gradient across the pulmonary valve by Doppler of the last examinations, one to 4 years after the procedure (mean 1.9 years), was 23.05 ± 9.40 mmHg in 17 patients. The mean ratio of balloon size and pulmonary valve ring was 1.06. One patient still has a residual gradient of 54 mmHg and two were lost to follow-up. No serious complication was encountered during the procedures. Conclusion: Balloon pulmonary valvuloplasty is effective in the management of children with valvular pulmonary stenosis. The intermediate term result is excellent.
