Catheter ablation of ventricular tachycardia (VT) arising from the septal outflow region is difficult when the substrate is deep, scarred, and close to the conduction system. In that setting, conventional radiofrequency (RF) endpoints may be misleading, and pulsed-field ablation (PFA) is emerging as a ventricular energy source, although experience remains limited1.
