Hypoxic choking episodes due to airway obstruction occurred frequently from 4 months of age in a boy with 22q11 deletion, pulmonary atresia, ventricular septal defect, absent central pulmonary artery, tracheobronchomalacia, and an aberrant right tracheal bronchus. The tracheobronchial tree was compressed by a posteriorly displaced ascending aorta and right aortic arch with aberrant left subclavian artery and major aortopulmonary collateral arteries. Single-stage unifocalization and intracardiac repair plus aortopexy at 8 months resulted in resolution of the respiratory distress and heart failure.
