Fungal Ascending Aortic Aneurysm after Cardiac Surgery

A 52‐year‐old diabetic male was admitted due to 1‐month history of fever, fatigue, and mild shortness of breath. Three months prior to admission, he had undergone aortic valve replacement, with a prosthetic one, because of streptococcus viridans endocarditis complicated by severe aortic regurgitation. Transesophageal echocardiogram revealed prosthetic valve endocarditis with dehiscence of the aortic valve and an abscess cavity extending from the aortic root into the ascending aorta. Blood cultures and serology were negative. Due to clinical deterioration, despite antibiotic therapy, the patient was reoperated on and the aortic valve and ascending aorta were replaced with a homograft. Valve culture grew Aspergillus flavus. This case is an example of a rare but of increasing frequency complication after cardiac surgery. Considering the high mortality from this complication, early recognition is of paramount importance.
