Atresia of the aortic arch, with a collateral artery from the right subclavian artery supplying the descending aorta

Interrupted Aortic Arch Associated with AP Window and Complex Cardiac Anomalies: Multi Detector Computed Tomography Findings

Interrupted aortic arch is a rare congenital malformation of the aortic arch defined as a loss of luminal continuity between the ascending and descending portions of the aorta. In a simple interrupted aortic arch, only a ventricular septal defect and patent ductus arteriosus are observed. We present a rare complex form of type A interrupted aorta with an aortopulmonary window, an atrial septal defect, a ventricular septal defect, and a patent ductus arteriosus on multidetector computed tomography (MDCT) imaging.
