Overview

Aortic stenosis can be classified broadly in two main categories: acquired and congenital. Further classification according to the origin of the stenosis includes acquired calcification, acquired rheumatic disease, congenital bicuspid valve, congenital unicuspid valve, congenital hypoplasia of the annulus, congenital subaortic, congenital subvalvular, and congenital supravalvular.

Aortic stenosis may be classified into two main categories:

• Acquired

• Congenital
