Abstract
We present a rare case of double right coronary artery (RCA) arising from separate ostia. A 62 years old male patient was admitted with acute onset retrosternal chest pain. ECG was suggestive of sinus rhythm with intraventicular conduction delay and pathological q waves in D3 and avF derivations without any significant ST segment elevations. In the coronary angiography, we detected double RCA, each had its own ostium arising separately from right aortic sinus with complete occlusion seen in one RCA. Plaques were present in left coronary arterial system. Guidewires could not be passed in the completely occluded right RCA and conservative therapy was recommended. Double RCA is a congenital coronary anomaly with a potential of atherosclerotic coronary artery disease which needs regular monitoring.
