ABSTRACT

Dual right coronary artery (RCA) is one of the rarest coronary anomalies. We presented a 61-year-old male referred with non-ST-segment elevation myocardial infarction. Angiogram revealed a stenosis-free RCA and another RCA with total occlusion of the proximal segment and originating from the same aortic sinus was also found. Total coronary occlusion increases mortality in patients with NSTEMI. In this paper we discussed that the presence of dual RCA may actually prevent undesired cardiac events.
