Hypothesis-generating for coronary collaterals in hypoxia; larger studies needed before clinical consideration.
The human heart is vascularised by the Third coronary artery apart from the right and the left coronary arteries. The Third coronary artery, also called Supernumerary coronary artery takes origin from the anterior aortic sinus of the heart. It plays a significant role in collateral circulation of heart in conditions of chronic hypoxia.
