Background: Rapid and significant rise in esophageal temperature (ET) during radiofrequency ablation (RFA) for atrial fibrillation (AF) can be an indicator of an esophageal injury and limits our ability to achieve pulmonary vein isolation(PVI) by incomplete left atrial posterior wall (PW)ablation. The aim of this study was to evaluate the safety and efficacy of the EsoSure® (NEScientific, Inc., Waterbury, CT), a mechanical esophageal deviation tool, during AF ablation procedures.
Methods: We evaluated 85 patients from 4 centers in whom ET rise was limiting RFA lesion delivery on the PW. EsoSure was used to deflect the esophagus away from the ablation site. Barium was used to visualize and confirm esophageal displacement in all patients. Baseline demographics and complication rates were collected.
Results: The mean age of our sample was 65.75 ± 15, 54% were males and mean CHA2DS2VASc score was 2.4 ± 1.07. All pulmonary veins/roof were successfully isolated after EsoSure use. No rise in esophageal temperature was noted in any of the patients. At the end of 3 months of follow up, the most common complication was mild, self-limited dysphagia (7%). No other major complications were noted. (Table)
Conclusions: Mechanical displacement of esophagus during RFA with EsoSure device appears to be safe and efficacious in enabling adequate RF energy delivery to the PW for successful PVI without significant luminal temperature rise.
