Abstract
Pulmonary and aortic valvular stenosis were relieved by percutaneous balloon valvuloplasty during cardiac catheterization on 14 children aged 22 months to 18 years. Before dilatation the transpulmonary systolic pressure gradients ranged from 43 mmHg (mean 87. 8 mmHg) in children with pulmonary valvular stenosis. There were significant reduction in the transpulmonary systolic pressure gradient (mean 33.1 mmHg) immediately after balloon valvuloplas- ty except one patient in which left pulmonary artery stenosis was shown. Balloon pulmonary valvuloplasty appears to provide good relief of valvular stenosis. By balloon valvuloplasty in children with aortic valvular stenosis, transaortic systolic pressure gradient (220, 103, 119 mmHg) were decreased (65, 69, 96 mmHg respectively). Balloon aortic valvuloplasty appears to provide good relief of aortic valvular stenosis also.
Key Words: Pulmonary stenosis, Aortic stenosis, Balloon valvuloplasty
