Overview

Aortic valve stenosis — or aortic stenosis — occurs when the heart's aortic valve narrows. The valve doesn't open fully, which reduces or blocks blood flow from your heart into the main artery to your body (aorta) and to the rest of your body.

Your treatment depends on the severity of your condition. You may need surgery to repair or replace the valve. Without treatment, severe aortic valve stenosis can lead to death.
