Novel Impedance‐Guided Contact Mapping Technique for the Circular Multielectrode Pulsed‐Field Ablation Catheter

Year: 2026

Type: article

Abstract: Impedance-guided PulseSelect contact mapping (i-Pulse) adapts EnSite X Contact Index for a circular multielectrode PFA catheter, enabling real-time visualization of electrode-tissue contact without fluoroscopy. With ICE guidance, Δimpedance > 5% identified adequate contact, standardized tagging, and guided applications in three atrial fibrillation cases, achieving acute pulmonary vein isolation without complications.
