Figure 6. — Fixed-tissue gross image panel with examples of cross sections through pulmonary lobes after irrigated radiofrequency (IRF) or pulsed field ablation (PFA) deliveries that were made distant (distal) to the venous orifices 12 wk earlier. Clear evidence of collateral damage (circled) was observed in the IRF treated lobe, but no evidence of damage was found after PFA. Asterisks are inserted in or near pulmonary vein targets. PV indicates pulmonary vein.
