title: Successful balloon aortic valvotomy in a child with a pulmonary hypertensive duct and aortic valve stenosis.
abstract: A ten year old boy with pulmonary hypertension and a ductus arteriosus had severe aortic valve stenosis relieved by balloon aortic valvotomy. Subsequent aortic regurgitation was mild. This procedure avoided open heart operation, which would have been hazardous in this patient.
