Key result
Computer simulations suggest a cooled intraesophageal balloon minimizes esophageal wall lesions during radiofrequency ablation compared to no balloon or a non-cooled balloon.
Why the study?
Does a cooled intraesophageal balloon prevent thermal injury to the esophagus during endocardial surgical radiofrequency ablation of the left atrium in a finite element model?

Should not yet alter esophageal protection strategies in AF ablation; leaves open cooled balloon effects on atrial lesion transmurality and clinical translation.
Does a cooled intraesophageal balloon prevent thermal injury to the esophagus during endocardial surgical radiofrequency ablation of the left atrium in a finite element model?
Computer simulations suggest that a cooled intraesophageal balloon can minimize esophageal thermal injury during left atrial radiofrequency ablation, though it may compromise atrial lesion transmurality.
Berjano et al. (2005) studied Atrial fibrillation. Cooled intraesophageal balloon vs. No balloon (collapsed esophagus) or non-cooled balloon was evaluated on Lesion depth in the esophagus (percentage of thickness of the esophageal wall). Computer simulations suggest a cooled intraesophageal balloon minimizes esophageal wall lesions during radiofrequency ablation compared to no balloon or a non-cooled balloon.
