Coronary arteries are the largest vasa vasorum of the heart, the heart develops from the fusion of two primitive endothelial tubes, which represent the ventral aorta. The right coronary artery arises from the right coronary sinus (anterior aortic sinus) of the ascending aorta and the left coronary artery arises from the left posterior aortic sinus of the ascending aorta. Ostia of the coronary arteries are located in the center of the corresponding aortic sinuses. Malformations of the position of the ostia and origin of coronary arteries lead to high risk of sudden death. Based on above findings the present study was planned to evaluate the coronary arteries in human cadavers. The present study was planned in Department of Anatomy, J.L.N.M.C. Bhagalpur, Bihar, India. Total 30 cases of the heart specimens were obtained from the cadavers in the Dept. of Anatomy. The present study on branching pattern and distribution of coronary arteries, shows some difference with respect to the results from the available literatures. The data generated from the present study concludes that knowledge about the variations of coronary arteries is helpful for cardiologists and radiologists in performing various procedures like coronary angiogram, coronary angioplasty, and bypass grafting surgeries etc.
