Transcatheter aortic valve replacement (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.
