Aortic Valve Replacement Surgery

Aortic Valve Replacement Surgery

Surgery Overview

Surgery to replace an aortic valve is done for aortic valve stenosis and aortic valve regurgitation . During this surgery, the damaged valve is removed and replaced with an artificial valve. The valve replacement is typically an open-heart surgery.

A minimally invasive method to replace the aortic valve may be an option for some people. These methods include minimally invasive surgery or a catheter procedure.

How is it done?

During open-heart valve surgery, the doctor makes a large incision in the chest. Blood is circulated outside of the body through a machine to add oxygen to it (cardiopulmonary bypass or heart-lung machine). The heart may be cooled to slow or stop the heartbeat so that the heart is protected from damage while surgery is done to replace the valve with an artificial valve.

The artificial valve might be mechanical (made of man-made substances). Others are made out of animal tissue, often from a pig.

What To Expect After Surgery

You will recover in the hospital until you are healthy enough to go home. Depending on your overall health, you will likely go home a few days after surgery.

Surgery will likely involve a long recovery over several weeks. You will probably need to take 4 to 12 weeks off from work. It depends on the type of work you do and how you feel. In some cases, full recovery may take several months.

Why It Is Done

Aortic valve regurgitation

If your chronic regurgitation is getting worse and you have symptoms, you will likely have surgery. You might have surgery before you get symptoms, especially if your regurgitation is getting worse. If you have acute regurgitation, surgery will likely be done right away.

For help with this decision, see Aortic Valve Regurgitation: Deciding About Surgery.

Aortic valve stenosis

If you have symptoms of aortic valve stenosis, your doctor will likely suggest surgery to replace the valve. Most people who do not have symptoms do not need the valve replaced.

How Well It Works

Aortic valve regurgitation

Valve replacement surgery is the only cure for aortic valve regurgitation. It helps relieve symptoms and prevent heart failure. And it helps people live longer. 1

Aortic valve stenosis

Valve replacement surgery is the only effective treatment for people who have severe aortic valve stenosis with symptoms. 1 If you don't have surgery after you start having symptoms, you may die suddenly or develop heart failure. Surgery can help you have a more normal life span.


Valve replacement surgery has a high rate of success and a low risk of causing other problems if you are otherwise healthy. Although most people have successful outcomes, there is a risk of death and serious problems during surgery. Valve replacement surgery is high-risk for people who have a failing left ventricle and who have had a heart attack. About 5 or less out of 100 people who have valve surgery die. 2

If you have an aortic valve regurgitation or stenosis and have symptoms, the risks of not replacing the valve are greater than the risks of surgery unless you have other health problems that make surgery too dangerous.

Even if valve replacement surgery is a success, you may have problems after surgery, such as:

  • An increased risk of blood clots. These can break off and cause a stroke or heart attack. To reduce the risk of blood clots, you will take a blood-thinning medicine.
  • A need for another replacement valve. This will depend on the type of valve you get and how long you live after you have the surgery.
  • Incomplete relief from symptoms. Some types of valves do not have openings as wide as a normal valve for a person your size. This can limit how well the valve works to relieve your symptoms.
  • A valve that fails. There is a small chance that the valve will not work. Your doctor will need to check from time to time to make sure that your valve is working.

What To Think About

If you decide to have surgery, you and your doctor will decide which type of valve is right for you.
