    Abstract:
    Coronary artery anomalies are not uncommon, occurring in 1.3% (range = 0.3-5.6%) of the population, and are often an incidental finding in asymptomatic patients. Approximately 20% of coronary anomalies have potential for life-threatening complication, including myocardial infarction, arrhythmia, or sudden death early in life or during adulthood. Coronary artery anomalies are composed of a wide variety of disorders. Some, such as anomalous location of a coronary ostium, duplication of coronary arteries, or multiple ostia, become clinically significant only when another cardiac surgical procedure is necessary, and generally, surgical correction is not required in these patients. On the other hand, the diagnosis of anomalous origin of left coronary artery from pulmonary artery or from the opposite sinus with inter-arterial course is an indication for operation. Some anomalies like coronary artery fistulas, myocardial bridging, and coronary aneurysm require operation only when they cause clinical symptoms. Coronary artery anomalies should be included in the differential diagnosis of anginal symptoms, myocardial infarction, arrhythmia, or heart failure, especially in young patients. Increased awareness of these pathologies will lead to earlier diagnosis and treatment of a potentially life-threatening condition.
