Abstract 3231: Esophageal Capsule Endoscopy: Different Findings Based On The Anesthesia Protocol
Introduction: Left atrioesophageal fistula is a rare but devastating complication that can occur following catheter ablation of atrial fibrillation.
Methods: Fifty patients undergoing AF ablation for paroxysmal and persistent/permanent symptomatic atrial fibrillation refractory to AAD have been enrolled and randomized into 2 groups: those undergoing the procedure under conscious sedation with fentanil or midazolam (25 patients, group
and those receiving general anesthesia (25 patients, group
All patients underwent esophageal temperature monitoring during the procedure.
Radiofrequency energy was discontinued when the luminal temperature reached 39 C. After ablation all patients had capsule endoscopy to assess the presence for endoluminal tissue damage of the esophagus.
Results: The results are shown in the table⇓ below
Conclusion: The use of general anesthesia increases the risk of positive esophageal findings by capsule endoscopy
