Coronary artery anomalies are a diverse group of congenital disorders whose manifestations and pathophysiological mechanisms are highly variable, with a global incidence of 5.64% [1]. The classification of coronary anomalies is based on the abnormalities seen in one or more site of origin, course, termination and branches of the major coronary arteries. Some of these anomalies are common, while others are rare, like super-dominant right coronary artery (RCA) and left anterior descending artery (LAD) arising from the right coronary sinus [1].
