Mitral valve replacement involves removing your mitral valve and replacing it with a mechanical valve or a tissue valve drawn from an animal. Mechanical valves are made of metal or plastic; a risk associated with metal replacement valves is formation of blood clots around the valve. If you have a mechanical valve replacement, you will need to take anticoagulant medication for the rest of your life to prevent blood clots. A risk associated with tissue replacement valves is that they may need to be replaced.

Depending on the type of replacement surgery you need, the procedure may be open heart or it could be minimally invasive surgery or robotic heart surgery.

This procedure may be necessary if you have a mitral valve defect or disease or another heart or vascular condition. The purpose of the procedure is to improve blood flow through your heart, improving symptoms such as chest pain and shortness of breath.

What does mitral valve replacement treat?

When heart valves are severely malformed or destroyed, they may need to be replaced with a new mechanism. Conditions that may require you to have mitral valve replacement include mitral valve stenosis, mitral valve regurgitation, mitral valve prolapse and some vascular diseases.

Generally, valve repair is preferred over valve replacement, although every patient is not eligible for repair.

Why Ohio State is the best hospital for mitral valve replacement

The Ohio State University Wexner Medical Center offers both minimally invasive surgery and robotic heart surgery for mitral valve replacement.We offer integrated patient care provided by a structured heart disease team that includes cardiologists, surgeons, cardiac sonographers, interventional cardiologists and anesthesiologists.

What to expect during mitral valve replacement

Preparing for your procedure

Prior to your heart valve surgery, you’ll meet with your physician to discuss your medical history, medications you take and any questions you have. Tests you may have before heart valve surgery include:

  • Chest X-ray – A radiograph or picture of the heart and lungs including blood vessels, ribs and bones of the spine
  • Blood tests – Studies to detect enzymes that leak into the blood when the heart has been damaged and to detect infection and antibodies
  • Electrocardiogram (EKG/ECG) – A test that records the electrical activity of the heart
  • Cardiac catheterization – A procedure to check for problems in coronary arteries. A long, thin tube (catheter) is inserted into an artery or vein in the groin, arm or neck, then threaded to the heart. The physician injects a contrast solution into the artery and takes X-rays to check for blockage and other abnormalities.
  • CT angiogram (CTA - computed tomography angiogram) – An imaging procedure that uses CT technology to produce cross-sectional, detailed images of blood vessels
  • Echocardiogram (also called echo) – This test uses sound waves to assess the function and structure of the heart muscle and valves

If you use tobacco, you will be instructed to quit at least two weeks before surgery. Tobacco use can interfere with the blood’s ability to clot properly. Your physician can prescribe a nicotine-replacement product to help you stop tobacco use.

As in the case of most surgeries, your physician will ask you to not eat or drink a certain number of hours beforehand, often nothing after midnight the night before.

The area where your incision will be made is shaved and cleaned prior to surgery to reduce risk of infection. You will be given anesthetic medication to put you “to sleep” during surgery.

During your procedure

You are connected to monitoring equipment (electrocardiogram) to check your heart’s activity during the procedure. You also have an intravenous line in your arm to provide anesthesia throughout the procedure. A mechanical respirator breathes for you during the surgery, via a tube inserted in your windpipe. Another tube, inserted in your nose and through your throat, prevents air and liquid from pooling in your stomach. Still another tube, a catheter, is inserted into your bladder.

Heart valve surgeries require the use of a heart-lung machine. This keeps blood flowing during the procedure. The machine takes over this function for your body, and your body takes over again when the procedure is completed.

The surgeon makes an incision in your chest to access your valve. The replacement is made, your heart is restarted, and the heart-lung machine is disconnected. Traditional valve surgery takes several hours. An echocardiogram confirms that your new valve and your heart are both working properly.

If you have robotic heart surgery or minimally invasive surgery, the incision is much smaller, the procedure is faster, and the hospital stay and recovery time are shorter.

Recovery after valve replacement

If you have traditional heart valve surgery, you may remain in the hospital for as long as a week or two.

Your medical team will help you get up and about one or two days after surgery. You may feel stiff and sore, but it is important to breathe deeply and cough to clear fluids from your lungs. You will be allowed to eat normally in most cases.

After your surgery, you may need to take medication to prevent blood clots from forming on the new valve. You also may hear a mechanical valve clicking in your chest. This is normal.

If your job involves primarily sitting at a desk, you usually can return to work in four to six weeks.
