Surgical Treatment of Enterococcus Faecalis Mitral Valve Endocarditis Complicated with Mycotic Aneurysm

Enterococcus faecalis is a Gram-positive bacterium that can cause rapidly progressive endocarditis and requires urgent and aggressive treatment, including surgical intervention. Bacterial endocarditis may present itself with complications. Care should be taken when interpreting the differential diagnosis. In this article, we present a case of Enterococcus faecalis mitral valve endocarditis accompanied by subarachnoid hemorrhage and mycotic intracranial aneurysms, which are very rarely observed in the literature.
