[Prosthetic valve endocarditis caused by Gemella haemolysans].
Reported herein is the case of a 47 year old man with mitral and aortic bioprosthetic valves who developed endocarditis. Blood cultures turned out to be positive for Gemella haemolysans, a commensal of the upper respiratory tract. Proper antibiotic therapy was immediately started according to antibiogram, and continued after the acute stage of the disease had been overcome. The aortic prosthesis appeared much more to be incompetent at Doppler and aortography (from 2/4 to 3/4). At surgery, the gross appearance of the explanted xenograft was consistent with infective endocarditis. The case is described for the rarity of the etiology: only 6 cases of infective endocarditis from Gemella haemolysans are reported in the literature, but this is the first involving a prosthetic valve.
