We have reviewed our experience with 61 infants with the hypoplastic left heart syndrome and conclude that for approximately one half, salvage by intensive medical management and surgical palliation is possible. Provided that cardiac catheterization and selective angiocardiography demonstrate adequate blood flow in the ascending and transverse aortic arch, palliation may be accomplished by relief of pulmonary venous obstruction and, if necessary, the conversion of either excessive or diminished pulmonary arterial flow to an adequate amount.
