Interrupted Aortic Arch: Navigating Diagnosis, Management, and Beyond.

Congenital heart disease (CHD), the most common type of congenital anomaly affecting approximately 1% of all births, presents with altered blood flow and circulation due to structural defects. Interrupted aortic arch (IAA) is a rarer type of cyanotic CHD, which tends to present elusive, nonspecific symptoms in the immediate newborn period. As the pathology progresses, symptoms become severe and quickly life-threatening. Timely identification and intervention is crucial, often requiring astute clinical acumen by newborn nursery providers. We present a case report of a neonate with unknown IAA, type A, at birth. A discussion of the pathogenesis, diagnosis, and treatment of IAA follows the case presentation.
