A pulmonary allograft (valve taken from a cadaver) is then used to replace the person's own pulmonary valve.

There are 4 valves in the heart: tricuspid, pulmonary, mitral, and aortic. In the United States, surgeons perform about 106,000 heart valve operations each year. Nearly all of these operations are done to repair or replace the mitral or aortic valves. These valves are on the left side of the heart, which works harder than the right. They control the flow of oxygen-rich blood from the lungs to the rest of the body. See also on this site: Valve Disease.
