A rare case of isolated mitral valve endocarditis by Gemella
Gemella sanguinis is a very rare cause of infective endocarditis. Only 12 cases previously reported in the literature, only two of which involved exclusively the mitral valve. It is usually associated with a preexisting cardiac condition or oral infection/instrumentation. Valve replacement has been required in the majority of cases along with prolonged antibiotic course, resulting in successful outcomes.

Gemella sanguinis is an extremely rare cause of infectious endocarditis, with only 12 cases previously reported in the literature. Here we report the third known case of isolated mitral valve endocarditis secondary to G. sanguinis

A 53-year-old man with mitral valve prolapse and history of recent dental instrumentation presented with malaise, thigh and finger pain and new pansystolic murmur. He was diagnosed with severe mitral insufficiency due to infectious endocarditis secondary to G. sanguinis. He underwent mitral valve replacement and was treated with a long course of antibiotics.

G. sanguinis is a rare cause of infectious endocarditis with very few reported cases in the literature. In the majority of reported cases, a strategy of valve replacement along with a prolonged antibiotic course results in a good outcome for the patient.
