There is no medical treatment that reverses the progress of aortic valve stenosis.

Aortic valve replacement is the only solution to this problem. However, surgery is not always necessary. Aortic valve stenosis can be monitored with echocardiography if surgery is not initially indicated. In addition, for patients who are not candidates for surgical valve replacement, there are percutaneous and catheter-based valve replacement procedures available.

Balloon valvotomy may provide short term relief of aortic stenosis, but is considered palliative until valve replacement can be accomplished.

Aortic valve replacement is necessary when the aortic valve has become diseased. The aortic valve can suffer from insufficiency (inability to perform adequately) or stenosis.

If she is concerned about this she should speak to a physician. Aortic valve replacement may be necessary if her aortic valve has narrowed or is leaking.
