Abstract

Coronary artery anomalies are rare, and their incidence varies from 0.6% to 1.3%. Conventional angiography is a commonly used modality for the assessment of coronary artery anomalies, but it may not identify and define the anatomy of anomalous arteries due to the complexity of the course and three-dimensional orientation of the arteries. We present a rare case of duplicated right coronary artery (RCA) with separate ostium on 64-row multidetector computed tomography (MDCT). MDCT is better than conventional angiography in cases where selective catheterisation of either a single artery or ostium during catheter angiography has resulted in missing an important vessel. So far, 13 cases of duplicated RCA have been reported in the literature, and the features on MDCT were described only in three cases.
