Aortic stenosis (AS) is a narrowing of the aortic valve opening. This valve controls the flow of blood from the heart to a large artery called the aorta. This artery carries blood from the heart to the rest of body.
AS makes it hard for blood to flow out of the heart. It can lower the amount of blood that goes to the body and cause a back-up of blood into the heart. This back-up can raise pressure in the heart and lungs. AS can range from mild to severe.
