Balanced Double Aortic Arch Causing Persistent Respiratory Symptoms Mimicking Asthma in an Infant.

Double aortic arch (DAA) is a common form of complete vascular ring. The condition leads to airway obstruction and compression of the esophagus. A balanced type of DAA is an extremely rare anomaly. The anatomical aberration cannot be easily distinguished by transthoracic echocardiography when an infant has chronic respiratory distress. Herein we presented a case of an 11-month-old infant who had chronic respiratory distress and a balanced type of DAA.
