Aortic valve stenosis — or aortic stenosis — occurs when the heart’s aortic valve narrows. The valve doesn’t open fully, which reduces or blocks blood flow from your heart into the main artery to your body (aorta) and the rest of your body.
Your treatment depends on the severity of your condition. You may need surgery to repair or replace the valve.
Aortic valve stenosis ranges from mild to severe. Signs and symptoms generally occur when narrowing of the valve is severe. Some people with aortic valve stenosis may not have symptoms for many years.
Signs and symptoms of aortic valve stenosis may include:
- Abnormal heart sound (heart murmur) heard through a stethoscope
- Chest pain (angina) or tightness with activity
- Feeling faint or dizzy or fainting with activity
- Shortness of breath, especially when you have been active
- Fatigue, especially during times of increased activity
- Rapid, fluttering heartbeat (palpitations)
- Not eating enough (mainly in children with aortic valve stenosis)
- Not gaining enough weight (mainly in children with aortic valve stenosis)
