The coronary sinus drains through the posterior wall of right atrium at the orifice of the coronary sinus. [ 6 ] [ 1 ] This orifice is located at the posteroinferior aspect of the right atrium, just medial [ 1 ] and to the left of the orifice of inferior vena cava , [ 6 ] and between the inferior vena cava and the right atrioventricular orifice ...
The third sinus, the right posterior aortic sinus, typically does not give rise to a vessel. Coronary vessel branches that remain on the surface of the heart and follow the sulci of the heart are called epicardial coronary arteries. [1]
In the anatomy of the heart, the valve of the coronary sinus (also called the Thebesian valve, after Adam Christian Thebesius [1] [2] [3]) is a valve located at the orifice of the coronary sinus where the coronary sinus drains into the right atrium. [4] It prevents blood from flowing backwards into the coronary sinus during contraction of the ...
The coronary sinus is a large vein that drains into the right atrium, and receives most of the venous drainage of the heart. It receives blood from the great cardiac vein (receiving the left atrium and both ventricles), the posterior cardiac vein (draining the back of the left ventricle), the middle cardiac vein (draining the bottom of the left ...

The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
Key Points from 24/7 Wall St.: The maximum Social Security check in 2025 is $5,108. There’s a maximum check because there is a cap on how much income is used to calculate benefits.
Unlike most cardiac veins, the anterior cardiac veins do not end in the coronary sinus; instead, they drain directly into [2] the anterior wall of [citation needed] the right atrium. [ 2 ] References
