Transcatheter Aortic Valve Implantation (TAVI)

What To Expect

• While you are in the hospital, your doctors and nurses will monitor you to check how the new valve is working.
• You will receive information from the hospital about diet, activities, and medicine.
• You will need to have regular checkups with your doctor.
• Your doctor may suggest that you attend a cardiac rehab program. In cardiac rehab, a team of health professionals provides education and support to help you recover and prevent problems with your heart. Ask your doctor if rehab is right for you.
• You may take aspirin or some other blood thinner to prevent blood clots. If you get a blood thinner, be sure you get instructions about how to take your medicine safely. Blood thinners can cause serious bleeding problems.

Why It Is Done

TAVI is done to treat narrowing (stenosis) of the aortic valve. This is the valve between your heart and the blood vessel (the aorta) that carries blood to your body. TAVI may also be done to place a new valve in an existing tissue replacement valve.

How Well It Works

This procedure can help people who have aortic stenosis feel better and live longer.

But how well this procedure works depends on several things, such as other health problems that a person has. These include other heart problems. Doctors are still learning who might benefit the most from TAVI.

Because TAVI is a newer treatment, doctors don't yet know the long-term benefits or risks. They also don't know how long the valves will last. But research shows that they work well for at least 5 years.^{footnote 1, footnote 2}

Risks

TAVI doesn't involve open-heart surgery. But the procedure does have serious risks. Some risks last just a short time. Others are long-term.

Risks include:

• Heart block. This is a problem with the electrical system in the heart. It can cause a slow heart rate. If this happens, a person may need a permanent pacemaker.
• Injury to the blood vessel used to put the catheter in the heart.
• Serious bleeding problems.
• Leaking around the valve.
• Heart attack.
• Stroke.
• Death.
