Pulsed Field Ablation for Ventricular Arrhythmia in Repaired Tetralogy of Fallot

Key Points

• Focal pulsed field ablation may improve management of ventricular arrhythmia in treated patients.
• This case illustrates a potential intervention to prevent complications following pulmonary valve replacement.
• Assessment focuses on the role of pre-emptive substrate modification in patients with repaired tetralogy of Fallot.
• Further studies could establish the long-term efficacy and safety of this treatment approach in similar patient populations.
