Predictors of long-term success after high-density mapping-guided substrate ablation procedures for ventricular tachycardia in patients with ischemic cardiomyopathy.

ABSTRACT:

Introduction

High-density (HD) substrate mapping may increase success of catheter ablation targeting ventricular tachycardia (VT). However, despite its use, recurrent VT is not uncommon. We aim to investigate factors that are associated with outcomes after HD mapping-guided substrate ablation procedures for VT in patients with ischemic cardiomyopathy.

Methods

Observational cohort study includes patients with ischemic heart disease who underwent HD mapping-guided substrate ablation of VT. Baseline and procedural characteristics were associated with outcomes after VT ablation.

Results

VT ablation employing HD mapping was performed in 80 patients. Median follow-up was 2.3 years. VT-free survival at one, two, and five years were 65%, 49%, and 40%. One-, two-, and five-yea
