What is heart valve disease? Get to know the signs and symptoms.
Heart valve disease occurs if one or more of your heart valves don't work well. The heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves.
These valves have tissue flaps that open and close with each heartbeat. The flaps make sure blood flows in the right direction through your heart's four chambers and to the rest of your body.
Birth defects, age-related changes, infections, or other conditions can cause one or more of your heart valves to not open fully or to let blood leak back into the heart chambers. This can make your heart work harder and affect its ability to pump blood.
