We report the case of a 25-year-old male with palliated tetralogy of Fallot and pulmonary atresia presenting with thrombotic occlusion of a major aortopulmonary collateral artery to the right lung. Percutaneous intervention was successful in recanalizing this vessel, resulting in symptomatic improvement.
Keywords: Congenital; Heart Defects; Pulmonary Atresia; Tetralogy of Fallot.
