Abstract

Background: Right-sided infective endocarditis is uncommon, and isolated pulmonic valve infective endocarditis (PVIE) is rare. Chronic haemodialysis is a risk factor for developing infective endocarditis. but recurrent PVIE in this population is not well described.

Case summary: A 32-year-old male with end-stage renal disease on chronic haemodialysis and diagnosed with PVIE 6 months back due to Staphylococcus epidermidis without identified source of infection presented again with recurrent PVIE with methicillin sensitive S. aureus, new pulmonic septic emboli, and peri-graft fluid collection on imaging, which was explanted with negative follow-up culture.

Discussion: Through this index case, we describe the unique pathology of recurrent isolated PVIE and explore its diagnostic and management considerations.

慢性血液透析患者因再感染而复发的孤立性肺动脉瓣感染性心内膜炎：一个指标病例的描述和处理考虑。

背景：右侧感染性心内膜炎并不常见，孤立性肺动脉瓣感染性心内膜炎（PVIE）也很少见。慢性血液透析是发生感染性心内膜炎的危险因素。但在这一人群中复发性PVIE并没有很好的描述。病例总结：32岁男性，慢性血液透析终末期肾病患者，6个月前因表皮葡萄球菌感染确诊PVIE，感染来源不明，再次出现复发性PVIE，伴甲氧西林敏感金黄色葡萄球菌，新发肺脓毒症栓塞，影像学显示移植物周围积液，术后随访培养阴性。讨论：通过这个病例，我们描述了复发性孤立性PVIE的独特病理，并探讨了其诊断和治疗的注意事项。
