Study on the origin of third coronary artery in human cadavers and its clinical significance
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2017, Vol 4, Issue 3
Abstract
Introduction: Third coronary artery supplies right ventricular outflow tract, arises from anterior aortic sinus. It is a source for collateral coronary blood flow forming a vascular anastomotic bridge between the right and left coronary systems. Objectives: To understand coronary artery disease and for successful planning of coronary angiogram the knowledge on third coronary artery is very much necessary. The purpose of the study was to know if the origin of third coronary artery is from a separate orifice or a branch of right coronary artery as right conus artery. Materials and Method: After an ethical approval, 49 formalin fixed human cadaveric hearts were collected from department of Anatomy and Forensic medicine, Mysore Medical College and Research Institute, Mysore, India and a study was done on the origin of third coronary artery in human cadavers by dissection method. The data was analysed using SPSS computer software. Results: It was observed that the incidence of third coronary artery was 10.2%. Conclusion: Complete knowledge on third coronary artery is essential to understand the advances made in coronary artery bypass surgeries and newer methods of myocardial revascularisation.
