A total of 626 (97.2%) received a temperature probe. Esophageal position was categorized: (A) behind left pulmonary veins, (B) left ostial, (C) in the middle of left atrium, (D) right ostial, and (E) behind right pulmonary veins. The most frequent esophageal position was B\u2010C (<jats:italic>n<\/jats:italic>\u00a0=\u00a0201, 32.1%), followed by B (<jats:italic>n<\/jats:italic>\u00a0=\u00a0161, 25.7%), and C (<jats:italic>n<\/jats:italic>\u00a0=\u00a0147, 23.5%). The temperature was highest in A\u2010B positions (42.04\u00b0C) and in D\u2010E positions (41.70\u00b0C). There was a significant correlation between the endoscopically detected esophageal lesions (EDEL) and the esophageal position (<jats:italic>r<\/jats:italic>\u00b2\u00a0=\u00a0\u2212.115, <jats:italic>P<\/jats:italic>\u00a0=\u00a0.004) and the esophageal temperature (<jats:italic>r<\/jats:italic>\u00b2\u00a0=\u00a0.162, <jats:italic>P<\/jats:italic>\u00a0=\u00a0.000), but not with body mass index (BMI) (<jats:italic>r<\/jats:italic>\u00b2\u00a0=\u00a0\u2212.016, <jats:italic>P<\/jats:italic>\u00a0=\u00a0.688). Additional substrate modification in the left atrium resulted in significantly higher esophageal temperatures (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001) and more frequent EDEL (<jats:italic>P<\/jats:italic>\u00a0=\u00a0.049). An EDEL was found in 15 patients (2.3% of all patients, 5.6% of patients receiving endoscopy). Of those, the median esophageal temperature was 41.8\u00b0C (interquartile range [IQR]: 41.2\u201042.4). Neither esophageal position nor temperature during ablation was associated with arrhythmia recurrences (both <jats:italic>P<\/jats:italic>\u00a0&gt;\u00a0.400).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>EDEL depended on the esophageal position and temperature, but not on BMI.
