Aspergillus endocarditis

Abstract

Aspergillus endocarditis is a rare cause of fungal endocarditis caused by the hyaline mold Aspergillus. The disease most commonly occurs in persons who are immunosuppressed and has a high mortality. Clinical presentation is often with long standing fever, embolic manifestations, and often heart murmurs. Diagnosis of aspergillus endocarditis is often delayed due to the low propensity for Aspergillus to grow in blood culture. Aspergillus endocarditis is characterized by large vegetations and also by frequently being found on the walls of the heart and not on the valves and hence can be missed if not carefully looked for. Definitive diagnosis is often by a combination of microbiological culture and histopathological examination of obtained tissue. Ancillary serological tests like galactomannan assay and polymerase chain reaction also help in the diagnosis. Treatment of aspergillus endocarditis virtually always requires a combination of prolonged antifungal therapy and surgery to enable a cure for these patients.
