Aortic valve replacement is an open-heart surgery. It is done to replace a malfunctioning aortic valve with a new one. The replacement valve may be:
Aortic Valve–Opened and Closed

The aortic valve is located between the pumping chamber (ventricle) on the left side of the heart and the aorta (a major artery). The aorta carries oxygen-rich blood from the heart to the rest of the body. The valve should be closed while the heart is filling with blood. When the heart chamber squeezes to push blood into the aorta, the valve should open fully to allow blood flow.
Aortic valve replacement is done when the aortic valve is not working properly. The amount of oxygen-rich blood getting out to the body can be significantly decreased with a faulty valve.
Sometimes, the aortic valve is misshaped due to a birth defect. This is called congenital aortic valve disease. Other times, the aortic valve works well for years before becoming too stiff or too floppy to open and close fully. This is called acquired aortic valve disease. Sometimes this happens due to normal aging. With age, calcium build-up on the valve causes it to malfunction. The valve problem may also occur as a result of other conditions, such as:
If you are planning to have a valve replacement, your doctor will review a list of possible complications, which may include:
Some factors that may increase the risk of complications include:
Your doctor will likely do the following:
Leading up to your procedure:
Aortic valve replacement is done with general anesthesia . You will be asleep.
An incision will be made down the middle of your chest. The breastbone will be separated so that your heart can be reached. A heart-lung machine will be attached. The machine will act as your heart and lungs. This allows the doctor to stop your heart to safely work on the heart valve.
An incision will be made in the aorta. The damaged valve will be cut out and a new valve will be sewn into place. The aorta will then be sewn back together. The heart will be started up again and the heart-lung machine will be removed. The breastbone will be wired together. The skin incision in the chest will be sewn back together.
You will be monitored in an intensive care unit directly after surgery. When you awaken, you will notice that you are attached to a number of devices, including:
About 2-4 hours
Anesthesia will block pain during the surgery. The incision in the chest and breastbone will cause pain after the surgery. You will be given pain medicine to help manage the pain.
The usual length of stay is 5-7 days. The length of stay will depend on your overall health and your recovery progress. Your doctor may choose to keep you longer if complications arise.
You will usually be in the intensive care unit for 1-2 days. Then you will be moved to a regular hospital room, where you will stay for several more days. You will be allowed to walk soon after your surgery.
You may be given a device called an incentive spirometer. You will be asked to use it every couple of hours during the day. This helps keep your lungs as open as possible. This can help you avoid pneumonia.
You can expect to be able to resume your normal activities within about six weeks of surgery. You should follow your doctor’s directions regarding when you can begin to drive, exercise, lift things, and otherwise exert yourself.
After you leave the hospital, contact your doctor if any of the following occurs:
