What is Heart Valve Replacement?

This is surgery to replace a damaged heart valve. The heart's four valves, which open and tightly close, allow blood to flow from one chamber to another. The valves also allow blood to leave the heart through the large blood vessels. The valves make it so that blood can only flow forward when the heart squeezes. Usually, only one valve is replaced at a time. But, at times, one or more valves may need to be replaced. The new heart valves can be:

  • Mechanical (metal and plastic), such as a St. Jude valve
  • Made of tissue—most commonly from a pig (porcine valve) or a cow (bovine valve), but they may also be supplied by a human donor or even manufactured from your own tissue

  • Infected heart valves

If you are planning to have heart valve replacement, your doctor will review a list of possible complications, which may include:
