    VA ablation under VA-ECMO shows higher ECMO weaning rates but varies significantly between AMI and HFrEF-related electrical storms.

  • 2

    AMI-related electrical storms have dynamic arrhythmogenic substrates, while HFrEF-related storms involve stable fibrotic scars.

  • 3

    The study's main finding indicates that VA ablation does not improve 60-day survival, especially in AMI patients.

  • 4

    Ablation in AMI patients may not reverse ischemic injury, leading to potential unfavorable risk-benefit ratios due to high complication rates.

  • 5

    Early VA ablation may benefit patients where arrhythmia is the primary hemodynamic driver, necessitating etiology-stratified therapeutic decisions.
