(Stenosis, Aortic—Child; AS—Child)


Risk Factors

Factors that increase your child's chance of developing AS include:
Tell the doctor if your child has any of these risk factors.


The doctor will ask about your child’s symptoms and medical history. A physical exam will be done. The doctor may be alerted of AS by the following:
  • Abnormal chest sounds, such as a heart murmur or click
  • Noticeable chest heave or vibration when the doctor's hand is held over your child’s heart
To confirm the diagnosis, tests may include:


Mild AS will be monitored for any changes or complication. Treatment may not be needed right away.
Treatment options for moderate to severe AS may include:

Lifestyle Changes

If your child has moderate to severe AS, your child may need to avoid strenuous physical activity. For example, your child will not be able to play competitive sports.


In certain cases, your child may need to take antibiotics before dental appointments or surgical procedures. This is to prevent an infection that could affect his heart.


Severe AS may require surgery. Options include:
  • Balloon valvuloplasty —A balloon device is passed through the arteries to open or enlarge the aortic valve. This may provide relief of symptoms. Since the valve can become blocked again, this surgery may need to be repeated.
  • Aortic valve replacement —This is the surgical replacement of a defective heart valve.
