DETERMINANTS OF OUTCOME IN HOSPITALIZED INFANTS WITH CONGENITAL HEART-DISEASE

To identify determinants of adverse outcome in this era of early, definitive treatment, retrospective data were analyzed for 1988 on infants aged < 1 year with congenital cardiac disease hospitalized at The Johns Hopkins Hospital. In this cohort of 108 infants, 34% (37 of 108) had complex cardiac disease, 33% (36 of 108) had major extracardiac anomalies, 88 patients (81%) underwent 116 surgical procedures, 37% (40 of 108) were hospitalized for > 28 days and 29% (31 of 108) died during the first year. Univariate analysis showed that complex disease (i.e., severe ventricular hypoplasia, ventricular septal malalignment or outflow atresia), extracardiac anomalies, early initial presentation, and prolonged stay in the intensive care unit were significantly associated with infant death, whereas surgery was associated with a significantly increased rate of survival. The findings for complex disease and surgery persisted in multiple logistic regression analysis. It is concluded that outcome in most infants with congenital cardiac defects is now extremely favorable, and that major research and preventive efforts should focus on complex congenital cardiac defects.
