Interrupted Aortic Arch is a rare congenital heart defect due to complete luminal interruption between ascending and descending aorta. IAA in adults is extremely rare and mostly present as systemic hypertension with distal perfusion maintained by large systemic collaterals formed over years. IAA in adults can be either corrected surgically with an interposition graft or can be successfully managed with antihypertensive drugs alone based on clinical presentation. Herein, We present a case with an incidental finding of IAA associated with Coronary Artery Disease and how the selection of conduits for coronary revascularisation is affected in the face of diagnosis of IAA.
