Background The Barrx™ radiofrequency ablation (RFA) catheter system comes in several different variations and sizes and is widely used for the eradication of Barrett’s esophagus (BE). The Barrx™ 360 and 360 Express system is used to perform circumferential RFA, while the Barrx™ focal catheter system is used for secondary focal RFA or primary treatment of short-segment BE. We aimed to investigate the number and type of complications and device failures associated with the Barrx™ RFA catheter system. Method We analyzed post-marketing surveillance data from the Food and Drug Administration’s Manufacturer and User Facility Device Experience (MAUDE) database from August 2011 to August 2021. Results During the study period, 148 unique reports detailing 78 device issues and 87 patientrelated adverse events were identified. The most reported adverse events for patients were stenosis secondary to treatment (n=15, 17.24%), mucosal laceration of the esophagus (n=13, 14.94%), chest pain (n=10, 11.49%), and odynophagia/dysphagia (n=7, 8.05%). The most common device complication was failure of the device to deploy when activated (n=10, 13.82%). Other device malfunctions included material deformation/distortion (n=7, 8.97%), catheter breakage (n=6, 7.69%), connection problems between the generator cable and RFA device (n=6, 7.69%), and failure of the balloon to properly inflate (n=5, 6.41%). Conclusion Findings from the MAUDE database highlight patient and device complications that endoscopists should be aware of prior to RFA of BE with the Barrx™ RFA catheter system.
