Outcomes following catheter ablation for structural ventricular tachycardia stratified by left ventricular ejection fraction: A retrospective cohort study.

ABSTRACT:

Background

Despite advances in catheter ablation for ventricular tachycardia (VT), patients with lower left ventricular ejection fractions (LVEFs) tend to have worse outcomes. However, there is limited understanding of the periprocedural factors associated with recurrence, and whether LVEF directly influences outcomes.

Objectives

The study sought to evaluate the electrophysiological characteristics and outcomes of patients undergoing VT ablation, stratified by LVEF.

Methods

Adults (≥18 years of age) who underwent VT ablation at Mayo Clinic Rochester or Mayo Clinic Health System between January 1, 2012, and January 1, 2023, were included. Data were collected through chart review, and categorized by LVEF (<25%, 25%-49%, ≥50%). The primary outcome was VT recurrence. Logi
