title: Successful percutaneous balloon valvuloplasty of the aortic valve in an infant.
abstract: Percutaneous balloon aortic valvuloplasty was attempted in an eight-month-old infant with severe aortic valve stenosis. The procedure resulted in a fall in the resting transvalvular systolic pressure gradient from 106 mmHg to 40 mmHg and no aortic regurgitation. Clinical and Doppler echocardiography findings suggest persistent improved status 3 1/2 months after the procedure.
