Abstract

Introduction: The human heart is vascularised by the Third coronary artery apart from the right and the left coronary arteries. The first branch of the right coronary artery is the conus artery. This branch may arise separately from the anterior aortic sinus in 36% of the individuals which is sometimes termed a ‘Third coronary’ artery (TCA).

Objective: To detect prevalence of Third coronary artery among cadaveric human hearts.

Material & Method: After an ethical approval, 50 formalin fixed human cadaveric hearts were collected from Department of Anatomy as well as from mortuary of SGMH Rewa MP. India and a study was done on the origin of third coronary artery in human cadavers by dissection method.

Result:  Present study find that among 50 cadeveric human hearts 16 hearts having Third coronary artery i.e 32% taking as a separate opening from anterior Aortic sinus.

Conclusion: Sound knowledge on third coronary artery is essential to understand the advances made in coronary artery bypass surgeries and newer methods of myocardial revascularisation. Well developed collateral circulation through TCA may allow diagnostic and therapeutic interventions in patients with coronary artery disease.

Keywords: Third coronary artery, Anterior aortic sinus, Right conus Artery.
