Predictors of permanent pacemaker requirement in aortic stenosis patients undergoing self-expanding valve transcatheter aortic valve replacement using the cusp overlap technique.

ABSTRACT:

Introduction

Since TAVR was approved for lower-risk aortic stenosis (AS) patients, managing post-implantation conduction disturbances has become crucial, especially with self-expanding heart valves (SEV). This study aims to identify risk factors for conduction disturbances in such patients using a specific fluoroscopic cusp overlap (COL) technique.

Methods

This retrospective study analyzed AS patients who underwent TAVR with SEV from 2019 to 2022, excluding those needing pacemakers or valve-in-valve procedures. Patients were grouped by conventional (CON) and COL techniques, with outcomes monitored using Valve Academic Research Consortium (VARC)-2 criteria.

Results

In this cohort study of 114 patients, 17 were excluded due to pre-existing pacemakers. Forty-seven receiv
