Infective endocarditis (IE) refers to an infection involving the endocardial surface of the heart. Most of the cases of IE are known to occur due to infection by viridans Streptococci or Staphylococci species. Abiotrophia defectiva is known to cause less than 1% of cases of IE. Though rare, this organism can cause life-threatening complications such as septic embolization, destruction of heart valves, and heart failure if not detected and treated timely. Here we discuss a case of a 44-year-old female who presented to our tertiary care centre with complaints of fever and easy fatiguability for two weeks. After further investigations, she was finally diagnosed to have IE due to Abiotrophia defectiva. Imaging demonstrated the presence of embolic and valvular complications as well. Through this case, we highlight the importance of early detection and timely management of this condition in order to decrease the occurrence of fatal complications and mortality.
感染性心内膜炎（IE）是指累及心脏内膜表面的感染。已知大多数IE病例是由草绿色链球菌或葡萄球菌属感染引起的。惰性营养菌（Abiotrophia defectiva）导致的IE病例不到1%。尽管这种微生物罕见，但如果未及时发现和治疗，它可引起危及生命的并发症，如脓毒性栓塞、心脏瓣膜破坏和心力衰竭。在此，我们讨论一例44岁女性病例，该患者因发热和易疲劳两周就诊于我们的三级医疗中心。经过进一步检查，她最终被诊断为惰性营养菌所致的IE。影像学检查也显示存在栓塞和瓣膜并发症。通过这个病例，我们强调了早期发现和及时处理这种疾病的重要性，以减少致命并发症的发生和死亡率。
