Background: The coronary arteries are the first vessels that branch from the aorta In 90% of the individuals, the posterior descending interventricular artery arises from the terminal portion of the right coronary artery –right dominance. In almost 10%of the hearts, there is left dominance i.e., the left circumflex artery provides the posterior descending interventricular artery. The left dominance is associated with high mortality rate. Aims & Objectives: To observe the dominance pattern of the coronary arteries. Method: For the present study 40 embalmed cadaveric heart specimens were collected and studied for the coronary dominance pattern. The study was done on 102 angiograms and their reports at Cardiology Department Different views of angiograms were studied, Dominant pattern of Coronary Arteries were seen. Conclusion: In this study, it was found that in most cases Males (85%) and Females (90%) were Right Dominant. Co-Dominance and Left Dominance are of small percentage in both the genders.
