Mitral valve surgery can repair or replace your heart's mitral 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 mitral valve opens and closes to keep blood flowing in the proper direction through your heart. When the mitral valve does not close properly (mitral valve regurgitation) or is very tight and narrow (mitral valve stenosis), blood does not flow through the heart the right way.
You will be asleep during the surgery. The 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 while he or she works on your heart.
While your heartbeat is stopped, the doctor will repair or replace your heart valve.
After the doctor has repaired or replaced your mitral 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 or nurse call line 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.
Having surgery can be stressful. This information will help you understand what you can expect and how to safely prepare for surgery.
