Abstract
Double right coronary artery (RCA) is an extremely rare coronary artery anomaly. We aimed to report an atherosclerotic double RCA which appeared after primary percutaneous intervention performed to treat acute inferior myocardial infarction. This is the first case in the literature, which the coronary arteries that can be accepted as double RCA have been hidden by total atherosclerotic occlusion of the proximal part of the RCA. In this paper, also the definition, correct diagnosis, and appropriate diagnostic methods for double RCA were discussed.
Highlights
Double right coronary artery (RCA) is a very rare coronary anomaly
Primary percutaneous coronary intervention (PCI) was performed to the culprit RCA lesion by using bare metal stent
Control coronary angiogram demonstrated surprisingly that there were two parallel coronary arteries distal to the stent which could be diagnosed as atypical double RCA (Figures 1 and 2)
Summary
Double right coronary artery (RCA) is a very rare coronary anomaly It might be complicated with atherosclerosis and present with symptomatology of atherosclerosis. In this issue, we reported an atypical double RCA which appeared after primary percutaneous coronary intervention (PCI), performed to treat acute inferior myocardial infarction. Control coronary angiogram demonstrated surprisingly that there were two parallel coronary arteries distal to the stent which could be diagnosed as atypical double RCA (Figures 1 and 2). He was administered tirofiban infusion, followed up for four day at intensive care unit and discharged without any complication
