Anomalous aortic origin of coronary artery: For a challenging diagnosis, a transthoracic echocardiogram is recommended.

Abstract

Anomalous aortic origin of a coronary artery (AAOCA), especially the interarterial course of the right or left coronary artery, predisposes paediatric patients to myocardial ischaemia. This rare condition is a leading cause of sudden cardiac death. General paediatricians face challenges when diagnosing this anomaly, and they should pay particular attention to the recurrence of exercise‐related syncope without prodromal symptoms, chest pain and dyspnoea. An accurate transthoracic echocardiogram with Doppler colour flow mapping is the best method to use to identify AAOCA.ConclusionIdentifying an AAOCA is challenging, and we provide advice on clinical red flags and diagnostic approaches for general paediatricians.
