Abstract

Patterns of branches and distribution of right coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. Generally the right aortic sinus had one orifice, but sometimes had two orifices which were related to conal branch. The right coronary artery had mural coronary in 17.5% of cases. In the most of the cases, right coronary artery was dominent, and type 4 was most frequent. Descending septal artery was observed in 17.5% of cases. The atrial branches can be grouped as anterior, posterior and left atrial, and each group was composed of one or two branches when present. In 97.5% of cases, intermediate atrial branch was observed. The sinuatrial nodal artery was originated mostly from right coronary artery. The atrioventriclar branch was observed in 7.5% of cases. The ventricular branches can be grouped as right anterior, right posterior and left posterior, and composed of 3-6, 0-2, and 0-4 branches respectively. Right marginal branch showed great variation, and other branch originated from superiorto to it was found to distribute the apex of the heart. Based on the results, the authors depicts typical arrangement of the rignt coronary artery in Korean.
