An 18-year-old man with a history of right ventricle to pulmonary artery conduit implantation for repair of congenital heart disease and vasculitis requiring chronic immunosuppression with azathioprine presented to the University of Ottawa with bacteremia. A transthoracic echocardiogram revealed no abnormalities at the site of the conduit. A fludeoxyglucose positron emission tomography scan was subsequently obtained that demonstrated an infected right ventricle to pulmonary artery conduit. It is important to remember that, as is true for classic valve endocarditis, an unremarkable transthoracic echocardiogram does not rule out an infected conduit in this population, and nuclear imaging may have important diagnostic utility.
一名18岁男性，有因先天性心脏病修复而进行右心室至肺动脉导管植入术的病史，因血管炎需要使用硫唑嘌呤进行长期免疫抑制，因菌血症就诊于渥太华大学。经胸超声心动图显示导管部位无异常。随后进行了氟脱氧葡萄糖正电子发射断层扫描，结果显示右心室至肺动脉导管感染。需要记住的是，与经典瓣膜性心内膜炎一样，经胸超声心动图无异常并不能排除该人群中导管感染的可能，核成像可能具有重要的诊断价值。
