Valve of coronary sinus
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 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.[4]
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 (containing numerous small holes).
