Candida parapsilosis endocarditis on a prosthetic aortic valve with unclear echocardiographic features.

Fungal endocarditis is rare in comparison with bacterial endocarditis and is associated with a poor prognosis. Despite the proven reliability of echocardiography, false negatives are not uncommon and may influence the therapeutic strategy, as some reports have supported the efficacy of antifungal treatment alone. We report on a case of bioprosthetic aortic valve Candida parapsilosis endocarditis without typical echocardiograhy findings, which we treated with both antifungal and surgical therapy.
