Transcatheter aortic valve replacement (TAVR)

Transcatheter aortic valve replacement (TAVR) is a procedure to replace an aortic valve that is narrowed and doesn't open fully. The aortic valve is between the left lower heart chamber and the body's main artery. Narrowing of the aortic valve is called aortic valve stenosis. The valve problem blocks or slows blood flow from the heart to the body.

Transcatheter aortic valve replacement (TAVR) is a treatment for aortic valve stenosis. In this condition, also called aortic stenosis, the heart's aortic valve thickens and becomes stiff and narrow. As a result, the valve can't fully open and blood flow to the body is reduced. TAVR is an alternative to open-heart aortic valve replacement surgery. People who have TAVR often have a shorter hospital stay than those who have heart surgery to replace the aortic valve. Your doctor may recommend TAVR if you have: Severe aortic stenosis that causes symptoms such as chest pain and shortness of breath. A biological tissue aortic valve that isn't working as well as it should. Another health condition, such as lung or kidney disease, which makes open-heart valve replacement surgery too risky.

All surgeries and medical procedures come with some type of risk. Possible risks of transcatheter aortic valve replacement (TAVR) may include: Bleeding. Blood vessel problems. Problems with the replacement valve, such as the valve slipping out of place or leaking. Stroke. Heart rhythm problems and the need for a pacemaker. Kidney disease. Heart attack. Infection. Death. Studies have found that the risks of disabling stroke and death are similar among those who have TAVR and aortic valve replacement surgery.
