Answer

Congestive heart failure due to aortic valve insufficiency is the most common intracardiac complication of subacute endocarditis. It develops after months of untreated disease but may occur a full year following microbiological cure.

The complication of arterial embolization is second in frequency to congestive heart failure for both subacute and acute IE. The frequency of this complication has decreased, from 80% in the preantibiotic era to 15-35% today. The emboli are usually sterile because of the minimally invasive nature of the causative organisms (eg, S viridans).
