While catheter ablation has emerged as an effective treatment for electrical storm, the long\u2010term outcomes are still unknown. This study aims to evaluate the long\u2010term outcomes of catheter ablation in patients with electrical storm, focusing on mortality, ventricular tachycardia (VT) recurrence, and hospitalization rates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective cohort study at a single center, enrolling 65 patients admitted with electrical storm.

All procedures were completed without any fatalities and without significant complications in 93.85% of cases. During follow\u2010up, 22 patients (33.85%) received ICD therapies for VT. The median estimated survival time for the VT\u2010free survival was 43 months. The 12\u2010month mortality rate was 26.15%. Over the median follow\u2010up of 23 months, 40% of patients died, and 72% experienced a composite endpoint of death, VT recurrence, or hospitalization. Multivariate analysis identified reduced LVEF as the strongest predictor of mortality during follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>VT ablation is a safe and effective therapeutic option for managing electrical storm, providing high acute procedural success and allowing most patients to be discharged.
