Why the study?
Data are limited on the feasibility and safety of performing emergency catheter ablation in an out-of-hours setting for ventricular arrhythmia storm refractory to medical therapy.
Is emergency out-of-hours catheter ablation safe and efficacious compared to daytime ablation for refractory ventricular arrhythmia storm?
Comparison

Supports out-of-hours ablation feasibility in refractory VA storm; leaves open randomized confirmation of timing safety.
Is emergency out-of-hours catheter ablation safe and efficacious compared to daytime ablation for refractory ventricular arrhythmia storm?
Emergency out-of-hours catheter ablation for refractory ventricular arrhythmia storm is feasible and not independently associated with increased mortality or transplant compared to daytime procedures, despite higher baseline patient acuity.
