Clinical outcomes after ventricular tachycardia ablation with or without induction.

ABSTRACT:

Background

Substrate mapping may offer a safer alternative to ventricular tachycardia (VT) mapping by avoiding prolonged episodes of VT during catheter ablation. However, VT induction to gauge procedural efficacy is still routinely attempted following substrate ablation, thereby exposing patients to potentially unnecessary hemodynamic risk.

Objective

The purpose of this study was to assess the efficacy of VT ablation without VT induction.

Methods

Patients with implantable cardioverter-defibrillators who underwent VT ablation between August 2020 and May 2023 were assessed retrospectively. Ablation and induction strategies were determined by operator discretion. Patients with or without attempted VT induction were compared with respect to baseline characteristics and cl
