Tetralogy of Fallot (TOF) is a relatively common Congenital Heart Defect (CHD) known to correspond with 0.28 of every 1000 live births. Very rarely, TOF may be associated with other cardiac abnormalities, including Double Aortic Arch, a pathology that leads to the formation of a vascular ring that typically surrounds the trachea and esophagus that can potentially present in early childhood with symptoms of dysphagia and difficulty breathing. CT angiogram has been heavily relied upon as it also allows for 3D reconstruction and optimal visualization of the vascular ring pathology. This particular case presents an infant with TOF further complicated by double aortic arch that was reconstructed with 3D-CT angiogram to better visualize and understand the consequences of these congenital abnormalities on the cardiopulmonary system, as well as contribute to a fund of knowledge about the diagnosis and management of similar cases.
