The heart is a hollow muscular organ situated in the mediastinum of the thoracic cavity. Coronary arteries are the first branch of aorta, most commonly originating below the junction between the bulbous and ascending part of aorta. The right and the left coronary arteries take origin from ascending aorta from its anterior and left posterior aortic sinus respectively. Aim and Objectives- To observe the anatomical variations in left coronary artery. Material & Methods:The study was carried out on 120 human cadaveric hearts from the Department of Anatomy, IMC&H Indore (M.P.), AFMS&RC Faridabad (Haryana), DYSPGMC Nahan (HP). Result- In the present study Left Coronary artery (LCA) originated from Left posterior aortic sinus in all the specimens. Bifurcation of LCA was observed in 88.33% of specimens, trifurcation of LCA in 10% of specimens, quadrifurcation and pentafurcation of LCA was also observed in 1% of specimens respectively
