Aortic valvulotomy in neonates.

Abstract

Fourteen consecutive newborns, 1 month of age or younger (mean age 12 days; mean weight 3.5 kg), had aortic valvulotomy for critical life-threatening aortic stenosis. Seven infants died early and seven survived hospitalization. Clinical, laboratory, catheterization, operative and autopsy data were analyzed to determine factors relevant to success or failure.
