ANSWER:

The answer is A and C.

Aortic stenosis presenting in an adult may result from rheumatic fever or from a congenital valvular deformity.

– A congenital bicuspid valve is suscrptible to endocarditis and eventually develops calcification and symptomatic stenosis

– Aortic insufficiency commonly follows bacterial endocarditis.

– Aortic insufficiency may also result from dilatation of the aortic annulus due to an ascending aortic aneurysm, as seen with Marfan’s syndrome or, more rarely, syphilis.
