  Fig. 3. Color-coded representation of the pentaspline PFA catheter deployed at the left superior pulmonary vein (LSPV) during the PVI procedure in the EnsiteX system, LAO respective PA view. The PFA catheter is represented as five distinct bipoles each representing a spline. The color of each spline corresponds to the same EGM-color on the EP-recording system. The tip of the guidewire is represented as an orb

  Fig. 4. Illustration of the “shadow” visualization technique in the EnsiteX system, showcasing the positioning of the pentaspline PFA catheter after rotation for ablation coverage around the PV ostium. The PFA catheter is deployed at the LSPV in basket configuration, and left lateral superior view is used for optimal catheter visualization during rotation
