Patients undergoing radiofrequency ablation (RFA) therapy for atrial fibrillation, can sometimes experience insult or injury to the esophagus, due to the proximity of the esophagus to the RFA treatment area. This study utilizes a disposable capsule endoscope (Pillcam ESO) to assess the condition of a patient's esophagus before and after the RFA procedure, as the injury rate to the esophagus has not been established.

Condition Intervention

Device: PillCam ESO Capsule Endoscope

Study Type: Interventional

Primary Outcome Measures:
  • capability of the PillCam ESO 2 capsule endoscope to identify esophageal injury due to RFA therapy for atrial fibrillation [ Time Frame: 24-48 hrs post RFA, and 14 days post-RFA ]

Secondary Outcome Measures:
  • compare patient post-ablation symptoms to esophageal injury findings identified by PillCam ESO capsule endoscope [ Time Frame: 24-48 hrs post-RFA and 14 days post-RFA ]

Enrollment: 52
Study Start Date: September 2009
Study Completion Date: September 2010
