Abstract

50 specimens were collected from anatomy and forensic medicine department after postmortem for the present study. In angiographic as well as cast study of coronary vessels, it was observed that there were three types of anastomotic pattern between the coronary arteries right and left (LCA). The conus artery (branch of right coronary artery) was arising separately from anterior aortic sinus as third coronary artery and was present in 20% of specimen studied in present study. 84% of specimen of coronary arteries exhibited interesting variations, like the main trunk of LCA showed either a bifurcation or Trifurcation while in 14% cases showed Quadrifurcation (branching further into four rami) and in 2% cases, even Penta furcation (branching further into five rami) was observed.
