Long-Term Outcomes of Catheter Ablation in Ventricular Tachycardia Electrical Storm: A Retrospective Cohort Study.

ABSTRACT:

Background and objective

Electrical storm is a life-threatening condition commonly observed in patients with structural heart disease. While catheter ablation has emerged as an effective treatment for electrical storm, the long-term outcomes are still unknown. This study aims to evaluate the long-term outcomes of catheter ablation in patients with electrical storm, focusing on mortality, ventricular tachycardia (VT) recurrence, and hospitalization rates.

Methods

We conducted a retrospective cohort study at a single center, enrolling 65 patients admitted with electrical storm. All patients underwent catheter ablation The primary outcome was VT-related ICD therapies, while the secondary outcomes included all caused mortality, VT-related ICD therapies, repeat ablation, hospital
