Overview

Normal aortic valve have three leafs (tricuspid), but some valves have two leafs (bicuspid). Typically, aortic stenosis due to calcification of a bicuspid valve appears earlier, at 40 to 50 years of age, whereas that due to calcification of a normal valve appears later, at 70 to 80 years of age.

Pathophysiology and Natural History

A congenital bicuspid aortic valve may be associated with the development of either progressive clacific stenosis or regurgitation. The defect is the leading cause of acquired calcified aortic stenosis
