Anomalous coronaries are frequently encountered during the course of performing coronary angiogram. The prevalence varies from 0.6%-1.3%. We discuss here about the anomalous origin of coronary artery from the opposite aortic sinus as this by far is the commonest variant encountered. The other anomalies like coronary artery fistula, myocardial bridge and separate origin of left anterior descending and circumflex haven’t been discussed as they are either too rare or are not associated with the risk of sudden cardiac death. There has been profound increase in data to this respect as major institutes have published their data clarifying now the diagnostic and management algorithm in dealing with it. Anomalous origin of coronary artery has significant clinical implications due to its association with myocardial ischemia, lethal arrhythmia and even sudden cardiac death.
