Abstract

Background and Aims: With the increasing advancement in the cardiac imaging techniques, it is mandatory to have a proper knowledge in the anatomy of coronary arteries. The present study is conducted to find out the normal and variations of the branching pattern of coronary arteries in human cadaveric hearts. Coronary dominance was also analyzed. Materials and Methods: 50 human hearts preserved in 10% formalin were collected from our Department of Anatomy of our institution. Observations: In this present study, 8% of specimens had third coronary artery, the posterior interventricular arteries were two in number in 22% of specimens. Left coronary artery trunk gave two branches in 80% of the specimens and three branches in 20% of specimens. Right coronary dominance was in 72% of specimens and left coronary dominance was in 28% of specimens. Myocardial bridges were present in 18% of specimens. Conclusion: Studying the variations of coronary artery is helpful for the interventional cardiologist, radiologist and cardiovascular surgeons to interpret in diagnostic and therapeutic procedures.
