Aortic Valve Stenosis

The heart has four chambers - in the lower left chamber (left ventricle), the aortic valve works like a one-way gate. When your heart pumps, the aortic valve opens to let oxygen-rich blood flow from the left ventricle into a large blood vessel called the aorta.  Blood then flows through the aorta to the rest of your body.

Aortic valve stenosis means that this valve has narrowed and it can't open all the way. Your heart has to work harder to pump blood through the smaller opening. Your heart can do this for many years, but over time it gets worn out. It can no longer send out as much blood as your body needs. Surgery or treatment is required to replace or repair your faulty valve when this happens.

What are the symptoms of aortic valve stenosis?

  • Breathlessness with activity
  • Chest pain, angina-type
    • under the chest bone, may move to other areas
    • crushing, squeezing, pressure, tightness
    • pain increases with exercise, relieved with rest
  • Fainting, weakness, or dizziness with activity
  • Sensation of feeling the heart beat (palpitations)
