Randomized Study on the Effect of Oesophageal Temperature on the Incidence of Esophageal Lesions After AF Ablation

It's a randomized pilot study to evaluate the incidence of esophageal thermal injury after left atrial ablation for the treatment of atrial fibrillation according to three different strategies of esophageal temperature monitoring. These patients will be divided into 3 groups with different strategies of esophageal temperature monitoring: group 1 without monitoring, group 2 monitoring with single probe thermometer and group 3 monitoring with multi-probe thermometer. The primary end point will be the incidence of esophageal lesions assessed by upper endoscopy.
