One of the anatomical variants of coronary artery origin comprises the left circumflex coronary artery (LCx) and left anterior descending coronary artery (LAD) arising separately from the left aortic sinus. Hence there is no common left main coronary artery (LCA/LMCA).
It considered the commonest coronary arterial variant with a reported incidence of around 0.41-0.67% 1-2.
It is a benign anomaly that causes no hemodynamic impairment or ischemic consequences as there is no vascular compression and the proximal courses are normal. This variant is asymptomatic.
