ABSTRACT
BACKGROUND Barrett's esophagus (BE) is a metaplastic change in the normal esophageal squamous epithelium and is a well-recognized precursor of esophageal adenocarcinoma (EAC). Nowadays, focal radiofrequency ablation is a valid technique for BE treatment by inducing a superficial and focal thermic destruction of metaplastic tissues. According to the literature, the most frequent patient-related adverse events of this procedure are esophageal iatrogenic stenosis, mucosal laceration or perforation of the esophagus, chest pain, and odynophagia/dysphagia. Postoperative heart rhythm abnormalities have been reported very rarely. CASE REPORT A 74-year-old patient with HE was treated by radiofrequency ablation (RFA) with the Barrx™ catheter system. He had 2 symptomatic episodes of atrial flutter in the immediate postoperative period requiring an external electrical cardioversion to induce a return to sinus cardiac rhythm. After atrial flutter ablation, 2 more radiofrequency procedures were performed, without adverse events. A laparoscopic Nissen fundoplication was carried out with complete endoscopic and histologic eradication of BE after 12-month follow-up. To the best of our knowledge, this is the first reported case of atrial flutter after esophageal RFA. Different mechanisms acting on an anatomic predisposing substrate can potentially play a role in starting atrial flutter, and include inflammation, autonomic activation, and myocardial injury. CONCLUSIONS The occurrence of this new type of adverse effect could potentially modify indications and postoperative monitoring of RFA treatment for BE. Endoscopists should know the possibility of this procedural complication in high-risk patients and they should propose alternative techniques or implement close cardiac monitoring in the postoperative period.
