ALTE and Feeding Intolerance as a Presentation of Double Aortic Arch

Many children who are admitted to pediatric hospitals with the chief complaint of apparent life-threatening event (ALTE) are, in fact, well appearing by the time the inpatient medical team evaluates the patient. This presents a diagnostic and therapeutic challenge. We describe a case of a six-month-old full-term female presenting with an ALTE and found to have a double aortic arch, a congenital anomaly that usually presents with a more progressive onset of symptoms such as chronic cough, positional stridor, and feeding difficulties. This case highlights the importance of maintaining a broad differential in a patient presenting with findings of tracheoesophageal pathology on clinical exam.
