Prenatal diagnosis of congenital heart defects (CHDs) is increasingly common, but it is still unclear whether it translates to improved postoperative outcomes. We performed a retrospective cohort study of all infants (aged <1 year) who underwent surgery for CHDs from 2006 to 2011 at a single institution. Primary outcomes were in-hospital and 1-year mortality rates. Secondary outcomes were readmission within 30 days of discharge, postoperative length of intensive care unit and hospital stay, unplanned reoperation, and extracorporeal membrane oxygenation use. We used chi-square analyses, Wilcoxon rank-sum tests, Kaplan-Meier survival curves, and adjusted Cox proportional hazards models to compare outcomes. Of the 1,642 patients with CHDs, 539 (33%) were diagnosed prenatally. Patients with prenatal diagnoses were of a younger age and less weight at the time of surgery, had greater Risk Adjustment for Congenital Heart Surgery scores, and were more likely to be white, to have an identified syndrome, or to be born at term. Compared with those diagnosed postnatally, those diagnosed prenatally had a significantly higher unadjusted 1-year mortality rate (11% vs 5.5%, respectively, p = 0.03). Controlling for weight, surgical severity, race, age at surgery, prematurity, and the presence or absence of genetic syndrome, patients with prenatal diagnoses had significantly greater mortality at 1 year (adjusted hazard ratio 1.5, p = 0.03), as well as significantly longer intensive care unit and hospital stays. Infants with CHDs diagnosed prenatally had worse outcomes compared with those diagnosed postnatally. Prenatal diagnosis likely captures patients with more severe phenotypes within given surgical risk categories and even within diagnoses and thus may be an important prognostic factor when counseling families.
