Multimodality Imaging of Progressive Aortic Valve Endocarditis: From Endophthalmitis to Aorto-Atrial Fistula

Our case highlights an atypical presentation of aortic valve endocarditis after initial presentation with endophthalmitis. This case demonstrates the rapidity of evolution of aortic valve endocarditis through sequential, multimodal imaging, and features the importance of a multidisciplinary approach required for the management of complicated aortic valve endocarditis. A male in his mid-thirties was admitted to the hospital with left endophthalmitis and diabetic ketoacidosis. He was found to have aortic valve endocarditis and severe aortic insufficiency, which progressed to aortic root pseudoaneurysm and subsequently to aorto-atrial fistula in less than 72 hours, as demonstrated by consecutive multimodality imaging studies. After extensive surgical repair, post-operative recovery, and rehabilitation, he was discharged home with a good functional outcome. Sequential and multimodal imaging can be beneficial in diagnosing paravalvular infection early in its evolution, which is crucial for decision-making regarding medical and surgical treatment strategies.
