Heart valve surgery is used to repair or replace diseased heart valves.
There are four valves in your heart:
Aortic valve
Mitral valve
Tricuspid valve
Pulmonary valve
The valves control the direction of blood flow through your heart. The opening and closing of the heart valves produce the sound of the heartbeat.
Heart valve surgery is open-heart surgery that is done while you are under general anesthesia. A cut is made through the breast bone (sternum). Your blood is routed away from your heart to a heart-lung bypass machine. This machine keeps the blood circulating while your heart is being operated on.
Valves may be repaired or replaced. Replacement heart valves are either natural (biologic) or artificial (mechanical):
Natural valves are from human donors (cadavers).
Modified natural valves come from animal donors. (Porcine valves are from pigs, bovine are from cows.) These are placed in synthetic rings.
Artificial valves are made of metal.
If you receive an artificial valve, you may need to take life-long medication to prevent blood clots. Natural valves rarely require life-long medication.
