Aortic Stenosis Treatments

Treatment

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.

Severe AS may require surgery. 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. However, since the valve can become blocked again, this treatment is not a permanent solution.

Aortic Valve Replacement

This is the surgical replacement of a defective heart valve. Currently, there are two types of replacement valves used:

Bioprostheses—These valves are made from animals such as cows or pigs, and may last about 10-15 years. Blood-thinning medication is usually not needed with this type of valve.
Mechanical prostheses—These synthetic valves are more durable, and may last for 20–40 years. However, you will be required to take blood-thinning medication for the rest of your life to prevent blood clots.
