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 …

Introduction Radiofrequency (RF) ablation of the left atrium of the heart is increasingly used
to treat atrial fibrillation (AF). Unfortunately, inadvertent thermal injury to the esophagus can …

Background Esophageal thermal injury can occur after radiofrequency (RF) ablation in the
left atrium to treat atrial fibrillation. Existing methods to prevent esophageal injury have …

Background Severe endoscopically detected esophageal thermal lesions (EDELs) have
been associated with higher risk of progression to atrio-esophageal fistula (AEF) following …

Pulmonary vein isolation using radiofrequency ablation is an effective therapy in patients
with atrial fibrillation. However, the esophagus descends in close proximity to the posterior …

Introduction The IMPACT study established the role of controlled esophageal cooling in
preventing esophageal thermal injury during radiofrequency (RF) ablation for atrial …

Aims To evaluate the efficacy of oesophageal cooling in the prevention of oesophageal
injury in patients undergoing atrial fibrillation (AF) catheter ablation. Methods and results …

Introduction Catheter ablation of atrial fibrillation (AF) may lead to collateral damage to the
esophagus. We tested the hypothesis that luminal esophageal temperature (LET)-guided …

Objective: Atrio-esophageal fistula is an infrequent but devastating complication of catheter-
based ablation of atrial fibrillation (AF). Thermal esophageal injury may be the precursor of …

Atrioesophageal fistula is a life-threatening complication of ablation treatment for atrial
fibrillation. Methods to reduce the risk of esophageal injury have evolved over the last …
