Aortic Valve Disease entails damage to, and dysfunction of, the aortic valve, one of the four valves in the heart.
The most common valvular problem in old age is aortic valve disease.
The aortic valve is one of four valves that control the flow of blood into and out of the heart. In particular, the aortic valve controls the flow of oxygenated blood pumped out of the heart from the left ventricle into the aorta, the main artery leading to the rest of the body.
In either Aortic Stenosis or Regurgitation, the work of the ventricle increases. As a result, its muscular wall thickens (a condition known as hypertrophy) and the left ventricle may become larger (dilate).
