Heart Valve Replacement

What is heart valve replacement?

Sometimes a natural heart valve that is not working properly needs to be replaced surgically with a prosthetic valve. A prosthetic valve is a synthetic or tissue substitute for the natural valve. It is designed to mimic the natural valve's normal opening and closing motions. A prosthetic valve can replace any of the heart valves – mitral, aortic, pulmonary or tricuspid. Prosthetic heart valves are divided into two basic categories: synthetic mechanical valves and biological valves, which are usually made of animal tissue.

Your doctor will discuss with you whether heart valve repair or replacement is more appropriate for your condition. Doctors often recommend heart valve repair when possible, as it preserves your heart valve and might preserve heart function. But sometimes valve replacement is necessary and the best option.

Doctors might also evaluate if you're a candidate for minimally invasive heart surgery. Your doctor will discuss the benefits and risks of each procedure.

If you need heart valve surgery, if possible, choose a medical center that has performed many heart valve surgeries.

  • Mechanical valves made of long-lasting metals, carbon, ceramics and plastic were the first to be used in valve replacement surgery. They have been refined and improved since being introduced in the 1960s.
    • The major advantage of a mechanical valve is durability – they can last a long time.
    • A fabric ring is used to sew the valve to heart tissue.
    • Mechanical valves can lead to blood clots which may in turn cause a heart attack or stroke. To prevent clots, people with mechanical valves must take blood-thinning medications (anticoagulants) every day for the rest of their lives. This can have implications for women of childbearing age or for people who have a history of major bleeding. Depending on the type of blood thinners, you may require routine blood-testing to monitor your INR (international normalized ratio) to measure your blood’s tendency to clot.
    • A mechanical valve makes a soft clicking sound when it closes. This can bother some people.
  • Biological (also called bio prosthetic) or tissue valves are specially prepared natural valves that come from human donors or animals.
    • Animal source valves (a xenograph) – usually cows or pigs – are similar to valves in the human heart. They are tolerated well and are less likely to form blood clots than mechanical valves.
    • Human heart valves from a donated heart (an allograft or homograft) are tolerated well and tend to last longer than animal valves. Using human valves is uncommon.
    • Valves can come from your own tissue (an autograft). In a Ross (or switch) procedure, your functioning pulmonary valve is used to replace your damaged aortic valve. Your pulmonary valve is then replaced with a donated one.
    • People with biological valves need to take blood thinners in the short term.
    • Biological valves are not as durable as mechanical valves. They are more durable in the aortic position and in older patients.

Why might I need heart valve repair or replacement surgery?

Valve repair or replacement surgery is done to correct the problems caused by one or more diseased heart valves.

If your heart valve(s) becomes damaged or diseased, you may have the following symptoms:

  • Dizziness
  • Chest pain
  • Breathing difficulties
  • Palpitations
  • Edema (swelling) of the feet, ankles, or abdomen (belly)
  • Rapid weight gain due to fluid retention

There may be other reasons for your healthcare provider to recommend heart valve repair or replacement surgery.

What are the risks of heart valve repair or replacement surgery?

Aortic valve repair and aortic valve replacement surgery risks vary depending on your health, the type of procedure and the expertise of your health care team. To minimize potential risk, aortic valve surgery should generally be performed at a center with a multidisciplinary heart team experienced in these procedures and that performs high volumes of aortic valve surgeries.

Risks associated with aortic valve repair and aortic valve replacement surgery may include:

  • Bleeding
  • Blood clots
  • Valve dysfunction in replacement valves
  • Heart rhythm problems
  • Infection
  • Stroke
  • Death
