Infective Endocarditis Followed by Fungal Prosthetic Valve Endocarditis and Mycotic Aneurysm of the Common Iliac Artery / 日本心臓血管外科学会雑誌

ABSTRACT

A 44-year-old man with a history of remittent fever for 6 months was given a diagnosis of inf ective endocarditis of the aortic valve related to a congenital ventricular septal defect (VSD), although no bacterial growth was obtained by blood culture. After one week of antibiotic treatment, aortic valve replacement (AVR) and patch closure of the VSD were performed after debridement of infected tissue and vegetations involving the aortic root, pulmonary and tricuspid valves, and myocardium surrounding the VSD. Antibiotic treatment was continued postoper-atively, but elevation of C-reactive protein (CRP) persisted. Blood culture disclosed Candida albicans in the blood 3 months after AVR. Fungal prosthetic valve endocarditis (PVE) was suspected, therefore, aortic root replacement with a Free Style bioprosthesis and VSD re-closure were performed followed by continued systemic antifungal treatment. Five months after reoperation, the patient was readmitted with a high fever. A pseudoaneurysm of the left common iliac artery and complete obstruction of the external iliac artery were shown by contrast-enhanced computed tomography (CT). The aneurysm was resected without revascular-ization. This case presentation concludes that long-term whole body study with contrast-enhanced CT might be necessary even though complete eradication of the infected foci of the heart has been established.
