The objective of this study was to analyze the benefits associated with prenatal diagnosis of complex congenital heart disease (CHD) on preoperative morbidity, 30‐day and 1‐year mortality in this population.

This was a retrospective review of patients with complex CHD born at our tertiary care center over a 10‐year period. Date analysis using Student t test and chi‐square test.

The prenatal diagnosis of complex CHD was associated with significant reduction in the incidence of the following preoperative parameters: antibiotic use, mechanical ventilation, inotropic support, hepatic and renal dysfunction, and acidosis. These beneficial effects were more significant in ductal‐dependent cardiac anomalies. However …
