Transcatheter aortic valve implantation (TAVI) has recently emerged as a treatment option for patients with severe aortic valve stenosis (AS). For patients who are deemed inoperable for surgical aortic valve replacement (SAVR), TAVI has a significant mortality benefit compared to medical therapy. This review discusses established and emerging roles for multimodality imaging and focuses on the application of these technologies for patient selection, intraprocedural guidance, and the detection and quantification of acute and chronic complications of this novel procedure.
经导管主动脉瓣植入术(TAVI)最近已成为严重主动脉瓣狭窄(AS)患者的一种治疗选择。对于被认为无法进行外科主动脉瓣置换术(SAVR)的患者,与药物治疗相比,TAVI具有显著的降低死亡率的益处。本综述讨论了多模态成像已确立的和新出现的作用,并着重介绍了这些技术在患者选择、术中引导以及检测和量化这一新技术的急性和慢性并发症方面的应用。
