Tricuspid Valve Regurgitation


The tricuspid valve is one of four valves that regulate blood flow through your heart. It controls blood flow from the right upper heart chamber (right atrium) to the right lower heart chamber (right ventricle) by opening up so that blood can flow through and then closing shut to keep blood from flowing backward. When the tricuspid valve doesn’t close tight enough, and blood begins to leak (or regurgitate) backward into the right atrium when the right ventricle contracts, it’s known as tricuspid valve regurgitation. This results in the right atrium enlarging, which can change the pressure of the nearby heart chambers and blood vessels.
