Purpose Thermal damage to the esophagus is a risk from radiofrequency (RF) ablation of
the left atrium for the treatment of atrial fibrillation (AF). The most extreme type of thermal …

Background The posterior wall of the left atrium may promote atrial fibrillation (AF) due to its
propensity for fibrosis, in addition to a high prevalence of non-pulmonary vein triggers …

Background Active esophageal cooling reduces the incidence of endoscopically identified
severe esophageal lesions during radiofrequency (RF) catheter ablation of the left atrium for …

Background Endoscopically detected esophageal lesions (EDELs) are common following
pulmonary vein isolation (PVI) and may progress to atrioesophageal fistula (AEF). Objective …

Background Increased peak luminal esophageal temperature (LET) is associated with
increased risk of esophageal injury after left atrial posterior wall (LAPW) ablation. The …

Background Pulmonary vein isolation (PVI) implies unavoidable ablation lesions to the left
atrial posterior wall, which is closely related to the esophagus, leading to several potential …

Risks to collateral structures exist with radiofrequency (RF) ablation of the left atrium to
obtain pulmonary vein isolation (PVI) for the treatment of atrial fibrillation. Passive luminal …

(1) Background: Microwave ablation (MWA) is a common tumor ablation surgery. Because of
the high temperature of the ablation antenna, it is strongly destructive to surrounding vital …

Background Esophageal injury (EI) remains a concern when performing pulmonary vein
isolation (PVI) using the high-power short-duration (HPSD) technique. Objective We aim to …

Esophageal thermal injury is one of the most feared risks of ablation of the posterior left
atrium despite the various devices used to monitor esophageal temperature or deviate the …
