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.

It's al â¦ so called like tricuspid valve... but i learned it the AV-valve.he two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve.The two semilunar (SL) valves, which are in â¦ the arteries leaving the heart, are the aortic valve and the pulmonary valve.
