A Rare Case of Aortic Atresia and Interrupted Aortic Arch Type B Survival, Anatomic Importance of a Vertebral Artery and the Circle of Willis, a Case Report and Review of the Literature.

Aortic atresia with interrupted aortic arch is a rare and critical congenital cardiac anomaly. We report a unique case of Type B interruption with aortic atresia, in which cerebral and coronary perfusion were solely dependent on the left vertebral artery without alternative circulatory pathways within the thoracic cavity. The patient underwent successful single-stage biventricular repair and continues to demonstrate favorable neurodevelopmental progress.
