This review describes the assessment of the aortic valve by echocardiography and also the roles that multidetector CT (MDCT) and cardiac magnetic resonance have to play as complimentary imaging modalities. It describes how to resolve apparent discrepancies in grading aortic stenosis and discusses the management of apparently moderate stenosis associated with cardiac symptoms or left ventricular dysfunction. The role of cardiac imaging including three-dimensional (3D) echocardiography and MDCT scanning in the preparation for transcatheter aortic valve implantation and during and after the procedure are described. While echocardiography remains the mainstay of imaging, 3D modalities, notably MDCT, are increasingly useful and a multimodality approach is likely to become established as routine clinical practice.

这篇综述描述了超声心动图对主动脉瓣的评估,以及多探测器CT (MDCT) 和心脏磁共振作为互补成像方式所发挥的作用。它描述了如何解决主动脉狭窄分级中的明显差异,并讨论了与心脏症状或左心室功能障碍相关的明显中度狭窄的管理。描述了包括三维 (3D) 超声心动图和MDCT扫描在内的心脏成像在经导管主动脉瓣植入准备以及手术期间和之后的作用。尽管超声心动图仍然是成像的主要手段,但3D模式 (尤其是MDCT) 越来越有用,并且多模态方法可能会被确立为常规临床实践。
