However the coronary arteries are functionally end arteries and so these meetings are referred to as potential anastomoses, which lack function, as opposed to true anastomoses like that in the palm of the hand.

[citation needed] Although rare, several anomalous courses of the right coronary artery have been described including origin from the left aortic sinus. [9]

Alternately, the PDA can be a branch of the circumflex coronary artery (10%, known as left dominance) which itself is a branch of the left coronary artery. It can also be supplied by an anastomosis of the left and right coronary artery (20%, known as co ...
