Morphometric Analysis And Anatomical Variations Of Right Coronary Artery In “Human Cadaveric Hearts” In South Indian Population

Abstract

Aim And Objective: The study objective is to know the anatomical variations of “right coronary artery” through dissection method and to know its clinical significance. Materials And Methods: In this study, 45 heart samples were implied and approx 30 hearts were calmed from Anatomy Department of “SRM Medical College”. 15 hearts are calmed from the anatomy department of “Sri Ramachandra medical college”. “The right coronary arteries” were observed as well as dissected for its normal anatomy and for any variations, and observations were noted out. Results: The present study shows that during dissection of “right coronary artery”, the “coronary ostium” was examined in all the sample inside the “anterior aortic sinus”, in that 9 sample presents different ostium for “right conus artery” and 1 specimen presents a several ostium for “SA nodal artery” in the same sinus, right marginal artery was present in all specimen with average length of 7.36cms.And with respect to PIV branch, the coronary dominance in right - 75.56%, left – 13.3% and co dominance - 11.11%. Conclusion: In view of this detailed study, I would like to conclude that the noted variations of this artery would be of effective use to the interventional along with “cardiologist plus radiologist” to destine the abnormalities to provide excellent maintainer about “cardiac diseases” and interventional procedures.
