Prosthetic Valve Endocarditis Caused by Gemella sanguinis: A Consequence of Persistent Dental Infection

Late prosthetic valve endocarditis is usually caused by streptococci, staphylococci, gram-negative bacilli and candida. The authors report the first case of prosthetic valve endocarditis caused by Gemella sanguinis. The patients risk factors for the development of Gemella endocarditis were the persistent severe dental caries and the presence of prosthetic valves. The patient required surgical replacement of the infected valve but had a good outcome with preservation of cardiac and valvular function. Evaluation and treatment of the persistent dental infection before initial valvular surgery may have prevented secondary infection of the prosthetic valve.
