Pulsed Field Ablation Using a Lattice-Tip Catheter for Treatment of Ventricular Tachycardias.

The inability to create durable, high-quality lesions in the ventricles has limited ventricular tachycardia (VT) ablation outcomes. With pulsed field ablation (PFA), a new modality offers the potential to overcome limitations of conventional, thermal ablation. The lattice-tip catheter's design makes it a promising and versatile tool for ventricular ablation. Preclinical studies have shown that PFA using this system can penetrate scar and fat, create deep lesions, and address difficult ablation targets. Clinical data are scarce but suggest acute feasibility and safety. More research is necessary to evaluate whether this novel ablation system could take VT ablation to the next level.
