So, it does cause lesions, or should be expected to, but the lesions are not as deep and spare the vascular structure, so they heal inside of 14 days. I guess that's good news, but I wish the article had offered a current comparative with RF ablation. Also, I don't understand the retraction of the esophagus that was concluded as an 'event', as if the PFA encourages to the esophagus to shrink away from the energy being applied. Bizarre.
