Operations to replace poorly functioning heart valves are common procedures. They're done to improve the health and vigor of people with heart valve diseases. The surgeon who'll perform the operation is the best person to talk to about specific questions or concerns. He or she can best explain the details of the surgical procedure and recovery period. A replacement valve may be taken from another human heart (cadaver valve) or pig (porcine valve) or it can be a mechanical one.
