感染性心内膜炎(infective endocarditis, IE)是一种具有高发病率和高死亡率的疾病,主要累及心脏内膜、瓣膜以及大血管等结构,随着老年人心脏瓣膜退行性病变、人工瓣膜置换或心血管侵入性操作增加,感染性心内膜炎发生率呈现上升趋势,鉴于IE的高发病率和高死亡率,早期诊断和治疗显得尤为重要,随着影像学技术发展,超声心动图在IE诊断及治疗中应用广泛,其他影像学技术如心脏计算机断层扫描(CT)、磁共振成像(MRI)、18F-氟脱氧葡萄糖正电子发射断层扫描/CT (18FFDG-PET/CT)和白细胞单光子发射断层扫描/CT (WBC SPECT/CT)也发挥着重要辅助作用。在这篇综述中,简述了IE的诊断及治疗进展,重点阐述影像学技术在IE的应用及临床价值。Infective endocarditis (IE) is a disease with high morbidity and high mortality, mainly involving the endocardium, valves, large blood vessels, and other structures. With the increase of heart valve degeneration, prosthetic valve replacement, or cardiovascular invasive procedures in the elderly, the incidence of infective endocarditis is on the rise. In view of the high incidence and mortality of IE, early diagnosis and treatment are particularly important. With the development of imaging technology, echocardiography is widely used in the diagnosis and treatment of IE, and other imaging techniques such as cardiac computed tomography (CT), magnetic resonance imaging (MRI), 18F-fluorodeoxyglucose positron emission tomography/CT (18FFDG-PET/CT), and leukocyte single-photon emission tomography/CT (WBC SPECT/CT) also play an important auxiliary role. In this review, the progress of diagnosis and treatment of IE is briefly reviewed, focusing on the application and clinical value of imaging techniques in IE.
