Redo-TAVI with a balloon-expandable valve and the impact of index transcatheter aortic valve design

Transcatheter aortic valve implantation (TAVI) is increasingly used to treat younger patients with longer life expectancy. Consequently, it can be expected that a considerable portion of these patients will outlive their transcatheter aortic valve (TAV). In the event of TAV failure, redo-TAVI may be the preferred solution. However, redo-TAVI outcomes may vary depending on the patient’s anatomy and TAV-in-TAV combination. In this viewpoint, we highlight different TAV stent designs and leaflet positions and discuss their impact on specific aspects of TAV-in-TAV.
