Aortic valve stenosis - What it is

Aortic valve stenosis (also known as aortic stenosis) is a narrowing of the heart's aortic valve. Stenosis occurs when the valve leaflets thicken, stiffen or fuse, causing the opening to narrow. Consequently, the aortic valve is unable to open properly, blocking blood flow from the heart into the aorta and onwards to the rest of the body.

An obstruction of the aortic valve will cause the heart to work harder in pumping blood to the body. As a result, the amount of blood which is pumped is limited and the extra work burden weakens the heart muscle. 

Aortic valve stenosis - Symptoms

Symptoms for aortic valve stenosis include:
  • Shortness of breath, especially with exertion or when you lie down
  • Fatigue
  • Dizziness or fainting
  • Sensations of a rapid, fluttering heartbeat (heart palpitations)
  • Chest discomfort or pain
Aortic valve stenosis often does not show any symptoms, making early detection difficult. Some signs and symptoms may only show up after a doctor’s physical examination. These signs include:
