Aortic Stenosis

Also known as: Aortic valve stenosis, calcific aortic stenosis

What is ​Aortic Stenosis?

The aortic valve separates the heart's left ventricle from the aorta, which takes blood to the rest of the body. When someone has aortic stenosis, the aortic valve doesn't open as wide as it should. This prevents blood from flowing out of the heart at its customary rate.
