Noncoronary Sinus Pivot Implantation for Transcatheter Aortic Valve Replacement With Self-Expanding Valve for Aortic Regurgitation.

ABSTRACT:

Background

Our initial study suggested that patients undergoing transcatheter aortic valve replacement (TAVR) with a self-expanding valve for pure native aortic regurgitation (PNAR) had a lower rate of major adverse cardiac events (MACE) when the noncoronary sinus pivot implantation (NCPI) was achieved.

Objectives

This study enrolled patients with PNAR who underwent TAVR with self-expanding valves between January 2019 and April 2024, compared the NCPI strategy with the conventional approach, and analyzed factors associated with successful NCPI.

Methods

We divided 87 patients into an early (conventional) group of patients treated before February 2023 and a late (NCPI strategy) group of patients treated after February 2023. Then the patients were also categorized by suc
