Eustachian valve endocarditis (EVE) is a distinctly rare and underdiagnosed entity. We report 2 new cases caused by vancomycin resistant Staphylococcus aureus and Staphylococcus hominis diagnosed on transesophageal echocardiography (TEE). Although, 63% of Eustachian valve endocarditis is caused by Staphylococcus aureus, we report the first case of vancomycin resistant Staphylococcus aureus and first case related to implantable venous access systems. EVE is now seen more commonly in elderly population with diverse microbial cultures and antibiotic sensitivities. TTE is the first modality for investigation of EVE, however a negative TTE does not preclude the diagnosis, as only 88% of cases were diagnosed on TEE.
咽鼓管瓣膜性心内膜炎（EVE）是一种极为罕见且易被漏诊的疾病。我们报告了2例经食管超声心动图（TEE）诊断为由耐万古霉素金黄色葡萄球菌和人葡萄球菌引起的新病例。尽管63%的咽鼓管瓣膜性心内膜炎由金黄色葡萄球菌引起，但我们报告了首例耐万古霉素金黄色葡萄球菌病例以及首例与植入式静脉通路系统相关的病例。如今，EVE在老年人群中更为常见，其微生物培养和抗生素敏感性各不相同。经胸超声心动图（TTE）是EVE检查的首选方式，然而TTE结果为阴性并不能排除诊断，因为只有88%的病例是通过TEE确诊的。
