Prognostic Value of Antiarrhythmic Drug Suppression of Electrical Storm Prior to Ventricular Tachycardia Ablation.

ABSTRACT:

Introduction

Early ablation after electrical storm (ES) has been associated with improved ventricular tachycardia (VT)-free survival. Antiarrhythmic drugs (AAD) can acutely temper ES in some patients allowing for delayed elective ablation, but they may be ineffective in other patients, who may require urgent ablation. The prognostic impact of acute AAD efficacy for ES patients undergoing ablation is unclear and may help to inform timing of VT ablation. The purpose of our study is to compare the outcomes of patients with ES undergoing VT ablation based on acute AAD efficacy.

Methods

This retrospective study of patients with ES who underwent VT ablation at our institution between November 2018 and September 2023 compared those who underwent urgent ablation due to inefficacy of
