Active esophageal cooling for the prevention of thermal injury during atrial fibrillation ablation: a randomized controlled pilot study

Cory M. Tschabrunn et al.

Summary: Active esophageal cooling using the Attune Medical Esophageal Heat Transfer Device may reduce the occurrence of severe endoscopically detected esophageal thermal lesions, offering potential benefits in preventing complications following radiofrequency catheter ablation for atrial fibrillation.

Randomized comparison of oesophageal protection with a temperature control device: results of the IMPACT study

Lisa W. M. Leung et al.

Summary: Thermal protection of the esophagus significantly reduces ablation-related thermal injury compared with standard care. This method of esophageal protection is safe and does not compromise the efficacy or efficiency of the ablation procedure.

Temperature monitoring and temperature-driven irrigated radiofrequency energy titration do not prevent thermally induced esophageal lesions in pulmonary vein isolation: A randomized study controlled by esophagoscopy before and after catheter ablation

Dirk Grosse Meininghaus et al.

Summary: Monitoring of luminal esophageal temperature does not prevent ablation-induced esophageal lesions. Patients without temperature surveillance were not at higher risk, but temperatures exceeding 42 degrees Celsius were associated with an increased likelihood of mucosal lesions.
