The coronary arteries arise from the coronary sinuses immediately distal (superior) to the aortic valve and supply the myocardium with oxygenated blood. The coronary sinus is a posterior structure and lies adjacent to the commissure of the septal and posterior leaflets. It is present in all mammals, including humans.

It returns the majority of the blood supply for the left ventricle to the right atrium.

The atrioventricular node (abbreviated av node) is a part of the electrical control system of the heart that coordinates the top of the heart. This video covers the anatomy of the cavernous sinus (lateral sellar compartment), its location, drainage and function. The av node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles. It is a shorter structure that is half oval in its outline.
