Key result
Catheter ablation targeting the Purkinje network successfully eliminated ventricular premature depolarizations and prevented recurrence of ventricular fibrillation over a 10-month follow-up.

Does catheter ablation of the Purkinje network prevent ventricular fibrillation recurrence in a patient with post-MI VF storm triggered by VPDs?
Catheter ablation of the Purkinje network can successfully eliminate multifocal VPDs and prevent recurrent ventricular fibrillation storm following myocardial infarction.
Supports Purkinje ablation in refractory post-MI VF; hypothesis-generating case report leaving broader efficacy open.
Tabled 1KEY TEACHING POINTS•A possible cause of Purkinje network excitability after a myocardial infarction includes its relative resistance to ischemia owing to its exposure to cavitary blood.•Purkinje network ventricular premature depolarizations (VPDs) may originate from anatomically different sites, suggesting a more generalized activation of the Purkinje network.•Catheter ablation of Purkinje network VPDs may play a role in a patient in ventricular fibrillation storm with different VPDs that can be characterized as originating from there.

Mountantonakis et al. (2015) conducted a case report in Ventricular fibrillation storm post-myocardial infarction (n=1). Catheter ablation of the Purkinje network was evaluated on Recurrence of ventricular fibrillation. Catheter ablation targeting the Purkinje network successfully eliminated ventricular premature depolarizations and prevented recurrence of ventricular fibrillation over a 10-month follow-up.
