A Novel Technique for Transcatheter Aortic Valve Replacement in Pure Aortic Regurgitation.

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 non-calcified 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. (C) 2019 by The Society of Thoracic Surgeons
