We report a case of staphylococcus endocarditis of the mitral and aortic valves in an intravenous drug user (IVDU) complicated by abscess of the aortic root and aorto-left atrial fistula. Interestingly, the tricuspid valve was free of vegetation. Infective endocarditis in IVDUs more commonly involves right-sided valves; left-sided endocarditis is rare, indicates severe disease, or is a postmortem finding. This case illustrates the need for considering left-sided valve endocarditis in IVDU with septicemia, even if the tricuspid valve shows no evidence of vegetation.
我们报告了一例静脉注射毒品者（IVDU）发生二尖瓣和主动脉瓣葡萄球菌性心内膜炎的病例，该病例并发主动脉根部脓肿和主动脉-左心房瘘。有趣的是，三尖瓣未发现赘生物。IVDU中的感染性心内膜炎更常累及右侧瓣膜；左侧心内膜炎罕见，提示病情严重，或为尸检结果。该病例表明，即使三尖瓣未显示赘生物证据，对于患有败血症的IVDU，也需要考虑左侧瓣膜心内膜炎。
