Abstract

Transcatheter aortic valve replacement (TAVR) in pure aortic regurgitation (AR) is challenging, because of the subsequent difficulty in anchoring the transcatheter valve in a noncalcified device landing zone (DLZ). Prestenting can help to prepare a stable DLZ for TAVR in pure AR and prevent valve migration. Here we report the first-in-human implantation of an uncovered stent into a noncalcified aortic valve as a prestenting strategy to prepare an easy DLZ for TAVR in pure AR. We consider this technique a useful novel tool to improve device success, at least as long as specific TAVR devices for pure AR are lacking.
