Valve of coronary sinus
|Valve of the coronary sinus|
Interior of right side of heart. (Valve of the coronary sinus labeled at bottom left.)
|Latin||valvula sinus coronarii|
The valve of the coronary sinus (Thebesian Ring) (Not to confuse with Thebesian's Valve located in the brain stem's 4th Ventricle) is a semicircular fold of the lining membrane of the right atrium, at the orifice of the coronary sinus. It is situated at the base of the inferior vena cava.
The valve may vary in size, or be completely absent.
It may prevent the regurgitation of blood into the sinus during the contraction of the atrium.
This valve may be double or it may be cribriform.
