Aortic valve disease is a condition in which the valve between the main pumping chamber of your heart (left ventricle) and the main artery to your body (aorta) doesn't work properly. Aortic valve disease may be a condition present at birth (congenital heart disease), or it may result from other causes.
Types of aortic valve disease include:
Aortic valve stenosis
In this condition, the flaps (cusps) of the aortic valve may become thickened and stiff, or they may fuse together. This causes narrowing of the aortic valve opening. The narrowed valve isn't able to open fully, which reduces or blocks blood flow from your heart into your aorta and the rest of your body.
Aortic valve regurgitation
In this condition, the aortic valve doesn't close properly, causing blood to flow backward into the left ventricle.
Your treatment depends on the type and severity of your aortic valve disease. In some cases you may need surgery to repair or replace the aortic valve.
