When coronary angiog- raphy was performed later to evaluate his coronary anatomy, an interesting finding was found to be present in the right circulation. There were two different right coronary arteries originating from the right sinus of Valsalva with the same ostia (Fig. 1 and 2). In addition, Two right coronary arteries in right anterior oblique FIG. 2 projection during coronary angiography. one of them was normal, but the other one had atheroscle- rotic plaques. Right Coronary Artery (RCA) anoma- lies are rare. RCA arising from left anterior descend- ing coronary artery or from pulmonary artery is some- times seen.1,2However, double RCA (one normal, one atherosclerotic) with the same ostia is rarely detected.
