Transcatheter Aortic Valve Implantation (TAVI)

Transcatheter Aortic Valve Implantation (TAVI) is used to treat severe Aortic Stenosis, a condition in which the aortic valve becomes narrowed, obstructing the outflow of blood from the heart and thereby requiring the heart to work harder to pump blood around the body.

The procedure involves implantation of an artificial heart valve designed to be inserted into your heart so that it holds open and replaces your diseased aortic valve. It consists of a metal stent (made of steel or cobalt-chromium) which secures the device in its intended position inside your own valve, and valve leaflets (made of biological material derived from cows) to direct the flow of blood out of your heart.

TAVI now offers effective treatment to patients who are at high risk for conventional open heart surgery. It is also intended to prevent further damage to the heart from Aortic Stenosis and to prolong life, which medical therapy cannot do.
