Heart valves are like doors that open and close. The valves open to allow blood to flow into the next chamber of the heart or into one of the arteries, and then they shut to keep blood from flowing backwards. The tricuspid valve is on the right side of the heart and separates the right atrium and the right ventricle.Normally, the tricuspid valve opens when the right atrium contracts. This allows blood to flow down into the right ventricle.The tricuspid valve is closed when the right ventricle contracts, allowing blood to flow out to the lungs. In tricuspid regurgitation, the tricuspid valve does not close properly.eart valves are like doors that open and close.
