The introduction of transcatheter aortic valve insertion (TAVI) has transformed the care provided for patients with severe aortic stenosis. The uptake of this procedure is increasing rapidly, and clinicians from all disciplines are likely to increasingly encounter patients being assessed for or having undergone this intervention. Successful TAVI heavily relies on careful and comprehensive imaging assessment, before, during and after the procedure, using a range of modalities. This review outlines the background and development of TAVI, describes the nature of the procedure and considers the contribution of imaging techniques, both to successful intervention and to potential complications.
经导管主动脉瓣插入术（TAVI）的引入改变了严重主动脉瓣狭窄患者的治疗方式。该手术的应用正在迅速增加，所有学科的临床医生都可能会越来越多地遇到接受或已经接受过这种干预的患者。成功的 TAVI 严重依赖于在手术前后使用多种方式进行仔细和全面的影像学评估。这篇综述概述了 TAVI 的背景和发展，描述了该手术的性质，并考虑了影像学技术的贡献，包括对成功干预和潜在并发症的贡献。
