Tricuspid Valve Stenosis


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). When the opening of the valve is narrowed, it’s known as tricuspid valve stenosis, which obstructs blood flow between the right atrium and right ventricle and results in the heart having to work harder to send blood to the lungs and the rest of the body. It often coexists with mitral valve stenosis, a narrowing in the valve between the left upper heart chamber (left atrium) and left lower heart chamber (left ventricle).
