Background: Major arterial supply to the heart is by Right coronary artery and its branches. Coronary arteries are also called as vasa vasorum of the heart. According to Gray’s anatomy, 70% of the hearts show Right coronary dominance which indicates that Posterior inter ventricular artery arises from RCA in these cases and in such cases usually RCAs terminate beyond the crux of the heart (In Posterior interventricular sulcus - PIVS).The aim of this study was to find out the levels of termination of Right coronary artery and pattern of coronary dominance. Materials and methods: For this study, 55 human formalin fixed  cadaveric heart specimens were taken from the department of anatomy of SSMC, Tumakuru. Results: Right coronary artery(RCA) terminated beyond the level of the crux of the heart (PIVS) in 35 heart specimens and 72 .2 % were right coronary dominant. Conclusion: Our study results are helpful for the accurate interpretation of advanced radiological techniques like angiography especially the  termination levels of right coronary artery and it acts as a guide to cardiothoracic surgeons for  Coronary artery interventional surgeries and management of IHD.
Keywords: Right coronary artery, coronary dominance, termination levels.
