BACKGROUND
Several factors increase the risk of right-sided endocarditis. The tricuspid valve is usually involved in right-sided endocarditis cases. Infective endocarditis of the pulmonic valve is rare, and few cases of pulmonic valve endocarditis were reported previously.
CASE PRESENTATION
Here we describe a case of a 81-year-old Middle Eastern male patient, admitted to our hospital three times in a period of 2 months for fever and cough. He had Streptococcus oralis bacteremia with vegetation that was on the pulmonic valve. We diagnosed him with pulmonic valve endocarditis, and he was treated successfully with intravenous antibiotics.
CONCLUSION
It is important to keep high suspicion for isolated pulmonic valve endocarditis in patients with respiratory symptoms. Adequate dental care is important in patients with risk factors for infective endocarditis.
背景
有几个因素会增加右侧心内膜炎的风险。三尖瓣通常会涉及右侧心内膜炎病例。感染性心内膜炎的肺动脉瓣较为罕见，之前也很少有肺动脉瓣心内膜炎的病例报告。
病例介绍
这里我们描述了一个 81 岁的中东男性患者，他在 2 个月的时间内因发热和咳嗽而住院 3 次。他患有链球菌性口炎菌血症，并在肺动脉瓣上有赘生物。我们诊断为肺动脉瓣心内膜炎，他成功地接受了静脉内抗生素治疗。
结论
对于有呼吸道症状的患者，要高度怀疑孤立性肺动脉瓣心内膜炎。对于有感染性心内膜炎危险因素的患者，适当的口腔护理很重要。
