Culture of a prosthetic valve excised for streptococcal endocarditis positive for Aspergillus fumigatus 20 years after previous A fumigatus endocarditis

Abstract

Culture of a mitral valve prosthesis excised for streptococcal endocarditis yielded Aspergillus fumigatus. The patient had undergone valve replacement 20 years earlier for A fumigatus endocarditis. Data suggest that quiescent A fumigatus may have survived in a biofilm on the surface of the prosthesis. An antifungal therapy was initiated for 6 months.
