What is aortic valve replacement?

Aortic valve replacement gives you a new aortic heart valve. The new valve may be mechanical or made of animal tissue, often from a pig. Your doctor will talk with you before surgery about which type of valve is best for you.

The aortic valve opens and closes to keep blood flowing in the proper direction through your heart. When the aortic valve does not close properly (aortic valve regurgitation) or is very tight and narrow (aortic valve stenosis), blood does not flow through the heart the right way.

You will be asleep during the surgery. Your doctor will make a cut (incision) in the skin over your breastbone (sternum). Then the doctor will cut through your sternum to reach your heart.

The doctor will connect you to a heart-lung bypass machine, which is used to add oxygen to your blood and move the blood through your body. This machine will allow the doctor to stop your heartbeat and replace the valve.

After the doctor has replaced your aortic valve, he or she will restart your heartbeat. Then the doctor will use wire to put your sternum back together, and stitches or staples to close the incision. The wire will stay in your chest. The incision will leave a scar that may become less noticeable with time.

You will stay in the hospital for 3 to 8 days after surgery.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

What happens before surgery?

Having surgery can be stressful. This information will help you understand what you can expect and how to safely prepare for surgery.

Preparing for surgery

• Bring a list of questions to ask your doctors. It is important that you understand exactly what surgery is planned, the risks, benefits, and other options before your surgery.
• Tell your doctors ALL the medicines and natural health products you take. Some of these can increase the risk of bleeding or interact with anesthesia. Your doctor will tell you which medicines to take or stop before your surgery.
• If you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, be sure to talk to your doctor. He or she will tell you if you should stop taking these medicines before your surgery. Make sure that you understand exactly what your doctor wants you to do.
• You may need to stop taking certain medicines a week or more before surgery, so talk to your doctor as soon as you can.
• Before your surgery, you will speak with an anesthesia provider to discuss your anesthetic options, including the risks, benefits, and alternatives to each. This may be on the phone or in person.

Taking care of yourself before surgery

• Build healthy habits into your life. Changes are best made several weeks before surgery, since your body may react to sudden changes in your habits.
  • Stay as active as you can.
  • Eat a healthy diet.
  • Cut back or quit alcohol and tobacco.
• If you have an advance care plan, let your doctor know. If you do not have one, you may want to prepare one so your doctor and loved ones know your health care wishes. Doctors recommend that everyone prepare these papers before surgery, regardless of the type of surgery or condition.

What happens on the day of surgery?

• Follow the instructions exactly about when to stop eating and drinking, or your surgery may be cancelled. If your doctor has instructed you to take your medicines on the day of surgery, please do so using only a sip of water.
• Take a bath or shower before you come in for your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.
• Do NOT shave the surgical site yourself.
• Remove all jewellery, piercings, and contact lenses.
• Leave your valuables at home.

At the hospital or surgery centre

• Bring a picture ID.
• Before surgery you will be asked to repeat your full name, what surgery you are having, and what part of your body is being operated on. The area for surgery may be marked.
• A small tube (IV) will be placed in a vein, to give you fluids and medicine to help you relax. Because of the combination of medicines given to keep you comfortable, you may not remember much about the operating room.
• You will be kept comfortable and safe by your anesthesia provider. You will be asleep during the surgery.
• The surgery will take about 3 to 5 hours.

After surgery

• You will go to the intensive care unit (ICU) right after surgery. You will probably stay in the ICU for 1 or 2 days before you go to your regular hospital room.
• You will have a breathing tube down your throat. This is usually removed within 6 hours after surgery. You will not be able to talk or drink liquids while the tube is in your throat. After the tube is removed, your throat will feel dry and scratchy. Your nurse will tell you when it is safe to drink liquids again.
• As you wake up in the ICU, the nurse will check to be sure you are stable and comfortable. It is important for you to tell your doctor and nurse how you feel and ask questions about any concerns you may have.
• You will have a thin plastic tube, called a catheter, in a vein in your neck. It is used to keep track of how well your heart is working. This is usually removed in 1 to 3 days.
• You will have chest tubes to drain fluid and blood after surgery. The fluid and extra blood are normal and usually last for only a few days. The chest tubes are usually removed in 1 or 2 days.
• You will have several thin wires coming out of your chest near your incision. These wires can help keep your heartbeat steady after surgery. They will be removed before you go home.

Going home

• Be sure you have someone to drive you home.
• For your safety, you should not drive until you are no longer taking pain medicines and you can move and react easily.
• Arrange for extra help at home after surgery, especially if you live alone or provide care for another person.
• You will be given more specific instructions about recovering from your surgery, including activity and when you may return to work.

When should you call your doctor?

• You have questions or concerns.
• You don't understand how to prepare for your surgery.
• You become ill before the surgery (such as fever, flu, or a cold).
• You need to reschedule or have changed your mind about having the surgery.
