INTRODUCTION
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.
PRESENTATION OF CASE
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.
DISCUSSION
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 prolonged antibiotic course results in good outcome for the patient.
引言
血孪生球菌是感染性心内膜炎极为罕见的病因，此前文献仅报道过12例。在此，我们报告第三例已知的由血孪生球菌引起的孤立性二尖瓣心内膜炎病例。
病例介绍
一名53岁男性，有二尖瓣脱垂病史且近期有牙科器械操作史，出现全身不适、大腿和手指疼痛以及新出现的全收缩期杂音。他被诊断为血孪生球菌所致感染性心内膜炎引起的严重二尖瓣关闭不全。他接受了二尖瓣置换术，并接受了长期抗生素治疗。
讨论
血孪生球菌是感染性心内膜炎的罕见病因，文献报道的病例极少。在大多数报道的病例中，瓣膜置换联合延长抗生素疗程的策略可使患者获得良好预后。
