[A case of pulsed field ablation for refractory midmyocardial origin ventricular tachycardia in the left ventricle].

Pulsed field ablation successfully treated a refractory ventricular tachycardia case originating from the midmyocardial layer of the left ventricle.

• The case involved ventricular tachycardia with a midmyocardial origin in the left ventricle.
• Prior radiofrequency ablation had been ineffective for this patient.
• Pulsed field ablation was applied and resulted in clinical improvement.
• This represents a case report (n=1) of pulsed field ablation use in refractory ventricular tachycardia.

Pulsed field ablation, while widely used for atrial fibrillation, has limited reported experience in ventricular arrhythmias, particularly refractory structural ventricular tachycardia.

• Pulsed field ablation is described as a novel ablation energy for cardiac arrhythmias with unique advantages.
• Its application has been widely adopted for atrial fibrillation.
• Experience with its use in ventricular arrhythmias, especially refractory structural ventricular tachycardia, remains limited.
• This case report contributes to the sparse literature on pulsed field ablation for ventricular tachycardia.
