Mycotic aneurysms of aortic root and aorta-to-left atrial fistula complicating bicuspid aortic valve endocarditis.

Unlike root abscess, fistula formation is quite uncommon in aortic valve endocarditis. In this report, we describe a patient with subacute bicuspid aortic valve endocarditis complicated by aortic insufficiency, mycotic aneurysms of the aortic root and fistulous communication between the aorta and the left atrium and his recovery upon surgical treatment.
