Single Coronary Origin From Right Coronary Sinus With Intraseptal Course: How to Make Diagnosis by Echocardiography

We describe a rare case of a male adolescent with anomalous aortic origin of the left coronary artery from the right sinus with intraseptal course (L-ACAO-IS), which was diagnosed at transthoracic echocardiography. The case we presented confirms how echocardiography is accurate in the diagnosis of even challenging coronary artery origin anomalies such as L-ACO-IS. Coronary artery origin evaluation should be an integral part of echocardiography examinations in infants, children, and young adults, especially those undergoing physical activity. We also remark the importance of using multiple views including short axis, long axis, and modified (anteriorized) 4-chamber view which is very helpful for a better evaluation of coronary artery origin and their proximal course.
