Double aortic arch with aortic atresia and left-sided type B interruption.
Aortic valve atresia with interruption of the aortic arch is an extremely rare anomaly; only eleven cases of this anomaly have been reported to date. In the absence of additional sources of blood flow to the ascending aorta, aortic valve atresia with interruption of the aortic arch is fatal. We present, to the best of our knowledge, the first case of a live birth with aortic valve atresia and interrupted left aortic arch (type B) without evidence of an aorticopulmonary communication or ductal supply to the native ascending aorta. Instead, blood flow to the native aortic root was derived from a persistent right embryonic dorsal aorta.
