Pulsed Field Ablation for Incessant Scar-Related Ventricular Tachycardia: First U.S. Report

70 y/o woman with a history of ischemic cardiomyopathy with ejection fraction of 20% due to a large healed anteroapical infarction. She had previously undergone three prior endocardial radiofrequency ablations for scar-related ventricular tachycardia (VT) with the most recent procedure at our center 4 months prior to the current hospital presentation. During that procedure, three zones of deceleration were identified, and ablation terminated two VT morphologies along the septal aspect of the scar and the patient was rendered noninducible from multiple sites of stimulation within the left ventricle.
