奇异变形杆菌引起的感染性心内膜炎（IE）很少见。鉴于IE合并P.本文报告1例P引起的IE合并LVP的病例。奇迹一位83岁女性因泌尿道感染而入院，P。在血培养中发现了奇异现象。经食道超声心动图和心电图门控计算机断层扫描显示二尖瓣返流和一个从二尖瓣环背侧突出的肿块。我们诊断为IE导致的LVP，并进行了二尖瓣置换术和二尖瓣环补片成形术。因此，奇异变形杆菌可引起血流感染并导致IE，其可导致LVP。学习目的：奇异变形杆菌通常引起老年人的尿路感染，也可能引起血液感染;然而，很少知道它是感染性心内膜炎和左心室假性动脉瘤的病原体。然而，在临床环境中，临床医生应该知道，P。奇异性也可引起IE伴环形扩张。
Infective endocarditis (IE) due toProteus mirabilisis rare. Given that cases of IE complicated with a left ventricular pseudoaneurysm (LVP) caused byP. mirabilishave not been reported thus far, here we report a case of IE complicated with an LVP caused byP. mirabilis. An 83-year-old woman was admitted to our hospital for urinary tract infection, andP. mirabiliswas detected in blood cultures. Transesophageal echocardiography and electrocardiogram-gated computed tomography revealed mitral regurgitation and a mass protruding from the mitral annulus on the dorsal side. We made a diagnosis of an LVP due to IE and performed mitral valve replacement and patch plasty of the mitral annulus. Thus,P. mirabiliscan cause bloodstream infections and lead to IE, which may result in LVPs.<Learning objective:Proteus mirabiliscommonly causes urinary tract infection in older adults and is also likely to cause bloodstream infections; however, it is rarely known to be the causative agent of infective endocarditis and left ventricular pseudoaneurysms. However, in clinical settings, clinicians should be aware thatP. mirabiliscan also cause IE with annular extension.>
