Possible Complications

If you are planning to have a valve replacement, your doctor will review a list of possible complications, which may include:
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:
  • Smoking
  • Drinking
  • Chronic disease such as diabetes or obesity
Your risk of complications may also be increased if you have:
  • Other heart conditions
  • Lung conditions

What to Expect

Prior to Procedure

Your doctor will likely do the following:
  • Physical exam
  • Blood tests
  • Echocardiogram—This is a test that uses sound waves to produce a moving picture of your heart and its valves.
  • Electrocardiogram—This is a test of the electrical system of your heart.
  • Cardiac catheterization—For this test, a very thin tube is threaded through your aorta. Contrast dye is squirted through the catheter and x-ray images are captured. These images can reveal problems with the functioning of your aortic valve and also determine whether your heart arteries are free from disease.
Leading up to your procedure:
  • Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure, like:
    • Anti-inflammatory drugs
    • Blood thinners
  • Do not eat or drink anything after midnight the night before your surgery, unless told otherwise by your doctor.
  • Arrange for help at home after you return from the hospital.
  • Arrange to have someone drive you home when you leave the hospital.


Aortic valve replacement is done with general anesthesia. You will be asleep.

Description of the Procedure

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.

After the Procedure

You will be monitored in an intensive care unit after surgery. When you awaken, you will notice that you are attached to a number of devices, including:
  • Monitors to track your heart rate, breathing rate, blood pressure, and the percentage of oxygen in your bloodstream
  • A ventilator tube in your mouth and lungs to breathe for you, or an oxygen mask or tube to give you extra oxygen
  • Tubes to drain extra fluid from your chest
  • A tube that goes into your nose and down to your stomach to drain your stomach of excess fluid and gas
  • A catheter in your bladder to drain urine
  • An IV to provide fluids, electrolytes, and pain medications directly into a vein

How Long Will It Take?

About 2-4 hours

How Much Will It Hurt?

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 medication.

Average Hospital Stay

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 occur.

Postoperative Care

At the Hospital
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.
During your stay, the hospital staff will take steps to reduce your chance of infection such as:
  • Washing their hands
  • Wearing gloves or masks
  • Keeping your incisions covered
There are also steps you can take to reduce your chances of infection such as:
  • Washing your hands often and reminding visitors and healthcare providers to do the same
  • Reminding your healthcare providers to wear gloves or masks
  • Not allowing others to touch your incisions
At Home
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 exert yourself.
  • If you have a mechanical valve, you will have to take blood-thinning medications for the rest of your life. They are needed to keep clots from forming around the valve.
  • Depending on the type of valve you have, you will need to take an antibiotic whenever you have dental procedures or certain surgical procedures.
  • You may be referred to cardiac rehabilitation. This can help you regain normal functioning and reduce the chance of future problems.
