Aortic stenosis

Heart Disease

What is aortic stenosis?

Normally, blood passes from the left lower chamber of the heart, called the left ventricle, through the aortic valve into the main artery of the body, the aorta.

If the aortic valve becomes narrowed, or stenosed, the blood flow through it is reduced and the heart has to work harder to pump blood to the body.

Aortic stenosis is more common in men. It can be present at birth but is more likely to occur in older people.
