Aortic valve stenosis was relieved by balloon dilatation during cardiac catheterization on 9 children aged 1 month to 15 years. Aortic valve diameter was estimated by two dimensional echocardiography to assist in the choice of balloon size. Before dilatation the transaortic systolic pressure gradients ranged from 60 mmHg to 177 mmHg, (mean: 91 ±38 mmHg). There were signifeant reduction in the transaortic systolic pressure gradients immediately after balloon dilatation (mean: 38 ±15 mmHg). There were poor correlation between catheterization measured and Doppler predicted transaortic systolic pressure gradients. Balloon aortic valvotomy appears to provide good relief of aortic valve stenosis and to reduce the open heart surgery and morbidity in many cases.
