Coronary artery disease is one of the major causes of death in developed countries. Knowledge of the normal and variant anatomy of coronary circulation is an increasingly vital component in the management of congenital and acquired cardiac diseases. AIM AND OBJECTIVE The objective of this study is to know the normal pattern of coronary arteries with reference to its origin, course, branching pattern and variations supplemented by morphometric analysis by doing a neat dissection of the heart. MATERIALS AND METHODS A sum of 45 heart specimens were used for this study, 30 were collected from Department of Anatomy, SRM Medical College and 15 were obtained from the department of anatomy, Sri Ramachandra medical college Chennai. The right and left coronary arteries were dissected out, and findings were noted. RESULTS In the present study, the ostium diameter of left coronary artery(LCA) is greater than the right coronary artery, the branching pattern of LCA shows trifurcation and tetrafurcation. 20% of specimen shows separate ostium for right conus artery where it is called as third coronary artery, 2.22% of specimens shows a separate ostium for SA nodal artery, 2.22% of specimens shows origin of LCA above the supravalvular ridge. CONCLUSION A detailed study of coronary arteries and its variations would be of great use to cardiologist and interventional radiologist to predefine the abnormalities for better management in coronary artery diseases.
