Abstract

Epicardial ventricular tachycardia (VT) is disproportionately common in non-ischemic cardiomyopathy and is a potential cause for recurrent VT post-ablation. Epicardial ablation has improved outcomes in such cases but is associated with risk including coronary artery and phrenic nerve injury, pericardial effusion/tamponade, and epicardial fat limiting ablation lesion depth, amongst other risks1. Pulsed field ablation (PFA) technologies, either stand alone or in combination with radiofrequency ablation (RFA), may offer strategies for mid-myocardial and epicardial ablation via an endocardial approach.
