Aortic stenosis, also known as aortic valve stenosis, is the narrowing of the heart’s aortic valve. The aortic valve is one of four valves in your heart located between the aorta (the largest artery in the body) and the left ventricle, or major pumping chamber of the heart. Valves have flaps of tissue (leaflets) that open and close when the heart pumps. They keep blood flowing in the right direction through the heart. 

Aortic stenosis prevents the valve from opening properly and restricts blood flow from the heart into the aorta and to the rest of the body. The heart must work harder to pump blood. This can weaken the heart and reduce the amount of blood it can pump, leading to fatigue, dizziness and failure of the heart.

Aortic Stenois: What You Need To Know

Causes of aortic stenosis include:

  • Congenital heart defects – An infant may be born with an already narrowed aortic valve, or a bicuspid aortic valve (a valve that has two flaps instead of three).
  • Calcium deposits that build up on the valve 
  • Scar tissue resulting from rheumatic fever
