- Abstract: Double right coronary arteries (RCA) are very rare congenital anomalies of coronary artery. We report a case of double RCA with total occlusion, incidentally found by collateral flows. A 71-year-old patient underwent percutaneous coronary intervention of left coronary arteries for angina, and the presence of double RCA was missed at initial coronary angiography (CAG). About 20 months later, second CAG was performed due to recurrent angina, and the CAG showed newly developed collateral flow suggesting the presence of the other missed RCA. There was a total occlusion at missed RCA and the lesion was successfully revascularized with drug eluting stent. If there was no collateral flow, the other RCA could not be found and its critical lesion could not be managed properly. Our case suggests that collateral flow can be a useful clue in detecting coronary anomaly. Besides, it is important to fully understand coronary anatomy, not to miss uncommon coronary lesion.
