We present a case of interruption of the aortic arch (IAA) in association with aortic atresia. A pulmonary artery to ascending aorta fistulous channel at the level of the sinuses of Valsalva of the pulmonary artery was present and supplied the ascending aorta and coronary arteries. The communication had a significant length, so embryologically it is not an aortopulmonary window. There have been only three reported cases in the literature of IAA with aortic atresia; in none was a pulmonary artery to ascending aorta fistulous tract present.
