Asymptomatic esophageal perforation following high-power short-duration pulmonary vein isolation—A case of conservative cure

Mechanisms of action behind the protective effects of proactive esophageal cooling during radiofrequency catheter ablation in the left atrium

“…Inherently, safety concerns struggle against those of efficacy. 69 Antenna effects may also play a role, with both RF and PFA. Conflicting data have been published in regard to this with RF ablation, 4 , 13 , 70 , 71 but a recent study leveraging mathematical models suggests that there may be effects on PFA from the presence of a metal intracoronary stent near the ablation device from amplifying the electric field distortion already caused by the presence of the vessel.…”
