Cardiac ablations are common medical treatments for people with atrial fibrillation (Afib). During the ablation procedure, a cardiac electrophysiologist will thermally ablate, or burn off, defective heart tissue with radiofrequency or cryoablation technology. The esophagus is often in close proximity to the left atrium. Since the left atrial tissue is approximately 2mm thin, the heat can transfer through it to the esophagus in contact and cause thermal damage / lesions on the esophagus. In worst-case rare scenarios, an atrio-esophageal fistula, or hole between the esophagus and the heart, can occur which has a ~75% mortality rate. It would be ideal to move the esophagus away from the heart before or during the ablation procedure preventing thermal damage.
