Narrowing of the retroaortic space after repair of common arterial trunk (CAT) with interrupted aortic arch (IAA) is a well-known issue. We present a newborn with CAT, IAA, and functionally univentricular heart (tricuspid atresia) who underwent repair of CAT, IAA, and left ventricle-to-pulmonary artery (LV-to-PA) conduit placement with the Lecompte maneuver. The patient suffered from left bronchus compression postoperatively, which was relieved by tracheobronchial release.
