Pulsed field ablation with a pentaspline catheter for ventricular arrhythmias: First US series
Authors' conclusion
In this first US series, VT/PVC ablation using a pentaspline PFA catheter for large VT substrate modification or after acute RFA failure appeared effective and safe, with promising acute and mid-term follow-up results.
