Arrhythmias & electrophysiologyCohort study
Impact of ventricular tachycardia ablation in the setting of electrical storm based on patient risk profile
- Retrospective cohort study
- multicentre
- Inverse probability of treatment weighting (IPTW)-adjusted
Authors' conclusion
In patients with electrical storm, VT ablation was associated with lower 1-year mortality across both low- and high-risk profiles.
Study context
- Population
- Patients admitted for electrical storm, four French centres
- Participants
- 606 patients
- Exposure
- Catheter ablation (CA) vs No CA
- Outcome
- Mortality
- Follow-up
- 1 year
Main finding

Further findings
Exploratory interaction analyses
- iVT score, but not PAINESD, identified high-risk patients who may derive earlier survival benefit from ventricular tachycardia (VT) ablation
