Type A Quadricuspid Aortic Valve Infective Endocarditis Complicated by Multiple Aortocardiac Fistulae: Case Report and Brief Literature Review.

Aortocardiac fistulae (ACF) are exceptionally due to infective endocarditis; they are usually congenital, posttraumatic, or complicate aortic dissection. In infective endocarditis setting, their presence should prompt urgent surgery as patients can deteriorate rapidly. We report the case of a 78-year-old female patient with the first ever reported quadricuspid aortic valve infective endocarditis complicated by multiple aortocardiac fistulae. Additionally, we provide a brief review of ACF, in infective endocarditis and quadricuspid aortic valve.
