Abstract Introduction: Congenital heart defects (CHDs) carry significant morbidity and mortality in pediatric patients. This study determined the spectrum of CHDs based on fetal and pediatric autopsies. Methods: Autopsy reports over a 15-year period were reviewed. Postmortem findings were correlated with echocardiography records. Results: From 608 autopsies, 119 cases with CHDs were identified (11% of fetal, 53% of neonatal, 18% of infant, and 4.5% of childhood autopsies). Persistent left superior vena cava was the most common individual defect. 41% of cases had extracardiac malformations. 18.5% of cases had chromosomal abnormalities. Prenatal echocardiography was available in 52 cases, showing 85% correlation with autopsy findings. Defects missed by echocardiography were generally of mild severity. Conclusion: Postmortem examination is important to delineate the anatomy of CHDs, and recognize extracardiac malformations for identification of possible genetic syndromes. This information can be used for parental counseling and for assessment of accuracy of pre-mortem imaging studies.
