Introduction: Understanding the anatomy and its variations of coronary arteries forms the base for coronary artery disease diagnosis and planning of surgeries.
Aim: The relation between outer diameter of right conus artery in cadaveric hearts and coronary angiograms, the relation between the diameter of right conus artery with and without the presence of long branches in both cadaveric hearts and coronary angiograms.
Materials and Methods :
150 embalmed cadaveric hearts received from various south Indian states, which were preserved in various colleges of Tamilnadu and Pondicherry was used in this study. 150 coronary angiograms of patients from various south Indian states. Methods adopted was Dissection method and Coronary angiogram were utilized for the study . 
RESULTS: Out of 150 cadaveric heart  and 150 coronary angiogram , the outer diameter of right conus artery arising from right coronary artery in cadaver and in angiograms was compared the resulted p value is less than 0.0001 which is considered to be extremely statistically significant. The number of long branches and short branches are studied with regard to the diameter of right conus artery. Pearson’s correlation coefficient was 0.1716 which is positive.
CONCLUSION: The diameter of right conus artery in the cadaveric study differs with the angiographic study. Thediameter of right conus artery is more when having a long branch
