Material and Methods: Thirty human hearts were taken for the study. They were dissected and analyzed.

Results: In 70% of the specimens, right coronary artery reached the crux of the heart, in 16.67% it crossed the crux, and in 13.33% it didn’t reach the crux. No anomalies in the origin and course of left coronary artery was found. The average mean length of left coronary artery was 12.42 mm. In 46.67% the diagonal artery aroused from the circumflex artery and in 43.33% from left anterior descending artery. In 10%, left coronary artery trifurcated into left anterior descending, diagonal and circumflex branches. In 13.33% circumflex branch coursed to reach the crux of the heart, in 70% it reached between obtuse margin and crux, and in 16.67% it was short terminating at the obtuse margin. In 3.33% of the specimen, two parallel branches of right coronary artery were found to traverse in the posterior interventricular groove. In 40% the posterior interventricular artery didn’t reach halfway the length of the posterior interventricular groove, in 33.33% it reached the halfway and in 26.67% it traversed about 3/4th length of the groove. Right coronary dominance was present in 86.67% of the specimens and 13.33% were left dominance. Co-dominance wasn’t found.
