Coronary artery anomalies may be seen in 1-5% of coronary angiographies. Origin of the left coronary artery from right aortic cusp is a very rare anomaly and its incidence is about 0.15%. This anomaly could be presented by myocardial ischemia and even sudden cardiac death during exercise in young patients.
