There is increasing evidence on the utility of cardiac computed tomography (CCT) in infective endocarditis (IE) to investigate the valvular pathology, the extra-cardiac manifestations of IE and pre-operative planning. CCT can assist in the diagnosis of perivalvular complications, such as pseudoaneurysms and abscesses, and can help identify embolic events to the lungs or systemic vasculature. CCT has also been shown to be beneficial in the pre-operative planning of patients by delineating the coronary artery anatomy and the major cardiovascular structures in relation to the sternum. Finally, hybrid nuclear/computed tomography techniques have been shown to increase the diagnostic accuracy in prosthetic valve endocarditis. This manuscript aims to provide a contemporary update of the existing evidence base for the use of CCT in IE.
越来越多的证据表明，心脏计算机断层扫描（CCT）在感染性心内膜炎（IE）中对于研究瓣膜病变、IE的心外表现以及术前规划具有重要作用。CCT有助于诊断瓣周并发症，如假性动脉瘤和脓肿，并能帮助识别肺部或体循环血管系统的栓塞事件。通过描绘冠状动脉解剖结构以及与胸骨相关的主要心血管结构，CCT在患者术前规划中也已显示出益处。最后，核医学/计算机断层扫描混合技术已被证明可提高人工瓣膜心内膜炎的诊断准确性。本文旨在对CCT在IE中的应用现有证据基础进行当代更新。
