Pulsed-Field Ablation for Paroxysmal Atrial Fibrillation in a Pediatric Patient.

We report a case of a 12-year-old male patient presenting with paroxysmal atrial fibrillation (AF). Catheter ablation was indicated for symptomatic paroxysmal AF. The procedure was conducted utilizing a cardiac pulsed-field ablation technology (LEAD-PFA, JJET). Lesion creation followed a systematic protocol comprising two sets of four consecutive applications at 1800 V targeting pulmonary veins, plus fifteen applications in inter-pulmonary vein regions and pulmonary venous vestibule. AF was induced during left inferior pulmonary vein ablation and terminated post-procedure. This case represents a documented successful ablation of paroxysmal AF utilizing PFA technology in a pediatric patient. These findings suggest that PFA may constitute a viable and potentially superior therapeutic modality for young patients with AF.
