Vieussens valve of the coronary sinus
ID: vieussens-valve-of-the-coronary-sinus
The Vieussens valve, also known as the valve of the coronary sinus, is a structure located at the opening of the coronary sinus into the right atrium of the heart. It is a thin fold of tissue that acts as a valve, although it is not a true valve like the mitral or tricuspid valves in that it does not completely occlude flow.
