Abstract

Fungal endocarditis is a rare but serious form of infective endocarditis associated with high morbidity and mortality. Among fungal pathogens, Candida species are the most frequently isolated and commonly found in individuals with predisposing factors, such as prosthetic heart valves.

The clinical presentation of endocarditis is highly variable and nonspecific, often including symptoms and signs of embolization. In this paper, we present a case of fungal prosthetic valve endocarditis in which the initial presentation was an acute ischemic stroke. The initial misidentification of Candida famata was attributed to limitations in the presumptive methodology used through selective chromogenic culture identification. However, the surgical specimen underwent mass spectrometry, leading to the correct identification of Candida guilliermondii instead of Candida famata. Furthermore, we conducted a non-systematic narrative review of the literature on Candida endocarditis.

Our findings underscore the importance of considering fungal endocarditis in the differential diagnosis of patients with possible extracardiac complications, particularly those with a history of heart valve replacement. Early diagnosis and a comprehensive treatment strategy tailored by species identification and antifungal susceptibility testing are crucial in improving patient outcomes.
