Proteus species belong to the Enterobacteriaceae family and are gram-negative-rods, commonly known to cause urinary tract infections and asymptomatic bacteriuria in elderly patients with risk factors such as diabetes mellitus and urinary catheterization. However, Proteus species are rarely known to cause infective endocarditis. We present a case of an 85-year-old female who presented due to decreased responsiveness with urine and blood cultures growing . While she was being treated for her urinary tract infection, her echocardiogram showed vegetation on the left coronary cusp of the aortic valve and left pulmonic valve leaflet. Uncontrolled tachyarrhythmias and new-onset atrial fibrillation complicated the hospital course. Later, she became bradycardic during the hospital stay, and all rate-control medications were held. Unfortunately, she went into cardiac arrest and spontaneous circulation could not be established with resuscitation attempts and she expired. To our knowledge, this is a rare case of native valve infective endocarditis secondary to , leading to uncontrolled tachyarrhythmias and death.
变形杆菌属属于肠杆菌科，是革兰氏阴性杆菌，通常在患有糖尿病和导尿等危险因素的老年患者中引起尿路感染和无症状菌尿。然而，变形杆菌属很少引起感染性心内膜炎。我们报告一例85岁女性病例，该患者因反应迟钝就诊，尿液和血液培养均有细菌生长。在她接受尿路感染治疗期间，超声心动图显示主动脉瓣左冠状动脉瓣叶和左肺动脉瓣叶有赘生物。未控制的快速心律失常和新发房颤使住院过程复杂化。后来，她在住院期间出现心动过缓，所有控制心率的药物都停用了。不幸的是，她发生心脏骤停，复苏尝试未能建立自主循环，最终死亡。据我们所知，这是一例罕见的由……继发的天然瓣膜感染性心内膜炎病例，导致未控制的快速心律失常和死亡。
