Pulsed Field Ablation in Ventricular Arrhythmias.

Pulsed field ablation (PFA) is a novel nonthermal energy source for catheter ablation, which is potentially useful also for ablation of ventricular arrhythmias since it mitigates the risk of collateral damage to adjacent tissues and may better penetrate through the scar tissue. Solid-tip PFA within the great cardiac vein appears to be advantageous for arrhythmias originating from the left ventricular summit. The use of a large-footprint catheter that toggles between radiofrequency current and PFA may provide an additional advantage since it allows the development of larger lesions to modify myocardial substrate. More experience is expected in the next few years.
