Aortic Valve Stenosis

A narrowing of the aortic valve is referred to as aortic valve stenosis. The constriction causes the heart to pump more powerfully and thus increases the pressure load on the heart. It is one of the most widespread diseases, including one of the most serious, as it places an extremely heavy load on the heart muscle, resulting in excessive muscle growth (hypertrophic cardiomyopathy).
