Atrioventricular Canal Defect,Pulmonary Artery Sling,and Aortic Arch Anomaly in a Patient With Down Syndrome

Abstract

There is a high prevalence of congenital heart disease in patients with Down syndrome. Atrioventricular (AV) canal defects, ventricular septal defects, and a patent ductus arteriosus are most commonly seen. The authors present a patient with a unique constellation of findings, including an AV canal defect, pulmonary artery sling, and an aberrant right subclavian artery diagnosed on a screening echocardiogram. Additional imaging modalities confirmed this atypical concurrence of congenital heart defects and also proved the accuracy of echocardiography in diagnosing rare combinations of congenital heart disease.
