WebAug 18, 2022 · 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.
