XXXX in infancy. Ten years' experience including studies of postoperative ventricular function.

The surgical experience with @entity1700 ( @entity1700 ) at the Venderbilt Hospital between the years 1969 and 1979 was reviewed. Twenty-five @entity1 with @entity1700 were studied. All but one @entity1 presented at less than 1 year of age, and 11 @entity1 were operated upon in the first 2 weeks of life. Operative mortality rate was 20% (5/25). Four of the five deaths were in critically ill neonates requiring preoperative ventilatory support. All operative deaths were in @entity1 with @entity3885 . All operative survivors have been followed for a mean 4.5 years (6 months to 10 years). There have been no late deaths or cases of symptomatic @entity3885 . All @entity1 have had normal growth patterns. Ten @entity1 have been recatheterized. Pulmonary artery systolic pressure, which was markedly elevated prior to operation, fell to normal levels after operation. Ventricular function has been evaluated by quantitative angiocardiography in nine @entity1 before and after operation. Left ventricular size and function were markedly depressed preoperatively and rose to normal levels in postoperative survivors. Left atrial maximal volume was found to be 94% of normal values. These data support the contention that preoperative @entity3885 is the single risk factor predicting higher risk of @entity204 . The presence of severe @entity308 of left ventricular size and function preoperatively does not predict a higher operative risk, and postoperative survivors can expect normal ventricular function.
