Answer is A bicuspid aortic valve. congenital anomaly which manifests mostly after 60 and causes endocarditis. plus this patient has infective emboli into systemic circulation. plus strep viridans affects the damaged valve.

No, MVP is the MC risk factor for IE in US. (2-4% MVP).

Bicuspid aortic valve is the MCC of AS below the age of 70 (can happen at age 20-50 yrs).

Tricuspid aortic valve is involved in AS above the age of 70 yrs.

RHD can cause AS or AR at any age.

So,

AS in a young patient>>>>>>>>> Congenital biscuspid aortic valve

AS in an older patient >>>>>>>>> Tricuspid aortic valve involvement
