Figure 6From: The prevalence of coronary anomalies in a single center of Korea: origination, course, and termination anomalies of aberrant coronary arteries detected by ECG-gated cardiac MDCT High takeoff of the right coronary artery (RCA). The volume rendering image shows the origin of the RCA from the anterior surface of the ascending aorta approximately 2Â cm above the sinotubular junction. The first portion of the proximal RCA shows a hockey-stick type of configuration, with an acute-angle bend on its main stem, before returning to its regular course in the right atrioventricular groove.Back to article page
