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.
Your heart has four chambers. Blood pumps through these four chambers to the rest of your body. The blood in your heart flows from chamber to chamber through four different heart valves. The valves open and close to ensure that blood flows in the proper direction. Each heart valve is made up of thin but strong flaps of tissue (also called leaflets or cusps) that open and close about 100,000 times each day.
