A case of infective endocarditis involving the vestigial eustachian valve is presented and the available English medical literature is reviewed. Only 5 prior cases have been reported: 4 of those required transesophageal echocardiography for diagnosis, and the other was found at autopsy. This clinical entity is routinely missed on transthoracic echocardiography. Injection drug use is a common predisposing factor, and Staphylococcus aureus is the most commonly identified organism. This report broadens the differential diagnosis of endovascular infections in injection drug users and highlights the importance of transesophageal echocardiography for diagnosis in selected patients.
本文报告了一例累及残留咽鼓管瓣膜的感染性心内膜炎病例，并对现有的英文医学文献进行了综述。此前仅报告过5例：其中4例需要经食管超声心动图进行诊断，另一例是在尸检时发现的。经胸超声心动图通常会漏诊这种临床病症。注射吸毒是常见的诱发因素，金黄色葡萄球菌是最常鉴定出的病原体。本报告拓宽了注射吸毒者血管内感染的鉴别诊断范围，并强调了经食管超声心动图对特定患者诊断的重要性。
