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.
The mitral valve regulates the flow of oxygen rich blood from the lungs to pass from the left atrium to the left ventricle.There are two main diseases or malfunctions of heart valves: regurgitation (valve does not close tightly) and stenosis (valve does not open fully).itral Valve Regurgitation, Stenosis, and Prolapse. The mitral valve is referred to as atrioventricular valves because it is located between the left atria and the left ventricle.
