MDCT coronary angiography post processed images (MIP and VRT) showing RCA and LMCA arising from right coronary cusp with separate ostia with retro aortic course of long LMCA (colored blue) before trifurcating.
An aberrant origin of left main coronary artery from the right coronary aortic sinus is a rare anomaly. MDCT can depict the origin and course of involved coronary noninvasively.
