Blood is pumped by way of your heart in just one direction. Heart valves play a key function in this one-way blood movement, opening and shutting with every heartbeat. Pressure modifications on either facet of the valves trigger them to open their flap-like "doors" (known as cusps or leaflets) at just the proper time, then shut tightly to forestall a backflow of blood. There are four valves in the center: tricuspid, pulmonary, mitral, and aortic. Within the United States, surgeons perform about 106,000 heart valve operations every year. Nearly all of these operations are finished to repair or exchange the mitral or aortic valves. These valves are on the left facet of the guts, which works more durable than the precise. They management the stream of oxygen-rich blood from the lungs to the remainder of the body. If valve damage is mild, medical doctors could possibly treat it with medicines. If harm to the valve is extreme, surgical procedure to repair or substitute the valve could also be needed.
