溶血双生菌是一种革兰氏阳性球菌，兼性厌氧菌的粘膜。在极少数情况下，它已被确定为心内膜炎发展中的机会致病菌。在这里，我们描述了一例感染性心内膜炎的病人与二叶主动脉瓣。一位38岁男性主诉劳力性呼吸困难一个月。他被发现有白细胞增多症，他的血培养生长溶血双球菌。经食管超声心动图显示二叶主动脉瓣伴1.5 x 1.5 cm植物性肿块、重度主动脉瓣返流和主动脉根脓肿。患者开始静脉注射氨苄青霉素和庆大霉素。然后，他接受了机械主动脉瓣置换术和牛左心室流出道重建术。我们的病例强调了将非典型病原体视为感染性心内膜炎病原体的重要性。
Gemella haemolysans is a gram-positive coccoid, facultative anaerobe of the mucous membranes. In rare cases, it has been identified as an opportunistic pathogen in the development of endocarditis. Here, we describe a case of infective endocarditis in a patient with a bicuspid aortic valve. A 38-year-old man presented with the complaint of exertional dyspnea of one month duration. He was found to have leucocytosis and his blood cultures grew Gemella haemolysans. Trans-esophageal echocardiography showed a bicuspid aortic valve with 1.5 x 1.5 cm vegetative mass, severe aortic regurgitation, and an aortic root abscess. The patient was started on intravenous ampicillin and gentamycin. He then underwent mechanical aortic valve replacement and bovine reconstruction of the left ventricular outflow tract. Our case highlights the importance of considering atypical pathogens as causative agents of infective endocarditis.
