Successful surgical treatment for fungal endocarditis involving the aortic valve: report of a case

A 50-year-old man who had undergone successful aortic valve replacement for fungal endocarditis was presented. He had been doing well until October 1993, when he suddenly developed shock with high fever. In two weeks he recovered from septic shock with vigorous medical treatment including intravenous administration of antibiotics. The infecting organism was not detected on repeated blood cultures. Four months later he was admitted to our hospital because of left heart failure. Although he was afebrile on admission, a two dimensional echocardiogram revealed vegetation on the aortic valve and massive aortic regurgitation. Inflammatory signs persisted and the vegetation increased in size, and therefore an aortic valve replacement was performed. A surgical specimen of the aortic valve revealed perforation in each of three cusps and vegetation on the non-coronary cusp. Pathological exploration revealed typical colonies of fungi. Following the diagnosis of fungal endocarditis, administration of an anti-fungal drug was started. His post-operative course was uneventful, and there was no evidence of recurrence with the anti-fungal medication for one year postoperatively.
