What are alternative treatments to aortic valve replacement?

Usually none: If a patient is truly in need of an aortic valve replacement, this is usually because the valve is either too tight or too incompetent or both. These are mechanical problems which need a mechanical fix, medications will help the person for a while, but usually the definitive treatment is valve replacement.

None: When the aortic valve needs replaced, the aortic valve needs replaced. Mortality is high if not replaced.
