Abstract：
The eustachian valve (EV) is a vestigial structure found at the junction of the inferior vena cava and the right atrium, a remnant of the embryological sinus venosus that may persist throughout life. Right-sided infective endocarditis of the eustachian valve remains a distinctly rare and under-diagnosed entity. Commonly known risk factors of eustachian valve endocarditis (EVE) are intravenous drug use, in-dwelling intracardiac devices, and central lines, although more recently immunocompromised states, e.g. uncontrolled diabetes mellitus and old age, have been recognized as risk factors for the disease. Although Staphylococcus aureus has been the most commonly implicated organism, cases of infections with gram-negative organisms are emerging. We present a 47-year-old male with uncontrolled type 1 DM who initially presented to the ED with complaints of low back pain and dysuria and was later found to have eustachian valve endocarditis ultimately treated with intravenous antibiotics.
摘要：
咽鼓管瓣（EV）是在下腔静脉和右心房的交界处发现的一种残留结构，胚胎性窦静脉的残余，可能会持续一生。咽鼓膜的右侧感染性心内膜炎仍然是一种罕见且未被诊断的实体。咽鼓管心内膜炎（EVE）的常见危险因素是静脉用药，内置心内装置，和中心线，尽管最近免疫受损的状态，例如，不受控制的糖尿病和老年，已被认为是该疾病的危险因素。尽管金黄色葡萄球菌是最常见的牵连生物，革兰氏阴性菌感染的病例正在出现。我们介绍了一名47岁的男性，患有不受控制的1型DM，最初向ED提出下腰痛和排尿困难，后来被发现患有咽鼓管心内膜炎，最终用静脉抗生素治疗。
