Aortic valve stenosis — or aortic stenosis — is a type of heart valve disease (valvular heart disease).
The valve between the lower left heart chamber and the body's main artery (aorta) is narrowed and doesn't open fully. This reduces or blocks blood flow from the heart to the aorta and to the rest of the body.
Treatment of aortic stenosis depends on the severity of the condition. You may need surgery to repair or replace the valve.
Without treatment, severe aortic valve stenosis can lead to death.
