Transcatheter aortic valve replacement, also called TAVR, is a minimally invasive treatment for aortic valve stenosis. This animation shows how TAVR is performed.
Here's how TAVR works:
A thin flexible tube called a balloon catheter delivers a collapsible replacement valve to the heart.
The new valve is placed inside the diseased valve and expanded — pushing the old valve leaflets out of the way.
The new valve works like a healthy one, restoring normal blood flow from the ventricle.
