To the Editor:

In the December issue of the Journal, we read with enormous interest the article entitled "Ablation of atrial fibrillation and esophageal injury: effects of energy source and ablation technique" by Aupperle and colleagues. 1 Go The authors performed in vivo experiments on 39 sheep to evaluate the histologic changes induced in the esophagus by using atrial fibrillation ablation with different energy types, such as cryoablation, microwave, laser, and unipolar or bipolar radiofrequency, through 2 different approaches, endocardial and epicardial. They observed esophageal alterations in numerous cases and concluded that the most significant lesions (moderate and severe damage) were principally induced by endocardial unipolar radiofrequency and cryoablation. We would like to comment on a number of issues.

The esophageal thermal lesion, which is similar to those found in myocardial thermal lesions, is mainly based . . . [Full Text of this Article]
