(Stenosis, Aortic—Adult; AS—Adult)



If you have mild AS, your condition will be monitored, but may not need immediate treatment. If you have more severe AS, your doctor may advise you to avoid strenuous physical activity. If necessary, you may be given medications to help prevent heart failure. If needed, you may be prescribed medication, and surgery may be required.


You may be prescribed vasodilators to widen your blood vessels and/or statins to lower cholesterol.


Surgical options include:
  • Balloon valvuloplasty—A balloon device is passed through the arteries to open or enlarge the stenotic aortic valve. This may provide temporary relief of symptoms. But since the valve can become blocked again, this treatment is not a permanent solution.
  • Aortic valve replacement—During this open surgery, the defective heart valve is replaced with either a bioprosthetic valve or a synthetic valve.
  • Transcatheter aortic valve replacement—This surgery also involves replacing the defective valve. But this is minimally invasive surgery that involves inserting the replacement valve through a small incision in the chest or through an artery in the leg.
