Objectives: An intimate knowledge of the anatomy of coronary ostia does a self-evident pre-requisite for complete understanding of coronary artery diseases and for more intelligent planning of surgery. The present study is undertaken

1.        To measure the diameters of coronary ostia and the diameters of roots of coronary arteries.

2.        To note for accessory ostia

Materials and Method: 49 human hearts fixed with 10% formalin were collected from Department of Anatomy and Forensic Medicine, Mysore Medical College and Research Institute, Mysore. Ethical clearance has been taken for the above.
Morphometric study of coronary ostia was performed using Vernier callipers. Data obtained was statistically analysed.
Results: It was observed that the mean diameter of left coronary ostia was greater than right coronary ostia which were statistically significant.
A statistically significant decrease in diameter from coronary ostia to the roots of coronary arteries was observed.
Multiple coronary orifices were common in anterior aortic sinus.
Conclusion: The knowledge of coronary ostia becomes important to cardiac surgeons for selective intubation.
