Vagus Nerve Injury Post Radiofrequency Catheter Ablation for Atrial Fibrillation

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02562404
Recruitment Status : Completed

Brief Summary:
This study is an observational study designed to determine the extent of gastrointestinal (GI) post-procedure complications after Radiofrequency Catheter Ablation (RFCA) for atrial fibrillation (AF). This exploratory study will evaluate patient symptoms prior to the RFCA procedure, at 1 month post RFCA procedure, and at 3 months post RFCA procedure, through the administration of a questionnaire. The purpose of this study is to determine if vagus nerve injury resulting from RFCA for AF increases the risk of post-procedure GI complications that may present as temporary or permanent symptoms.

Primary Outcome Measures :
  1. Symptoms Associated with Vagus Nerve Injury [ Time Frame: At RFCA procedure, 1 month post RFCA procedure, 3 months post RFCA procedure ]
    The composite of symptoms associated with vagus nerve injury: increased heart rate, bloating, early satiety, heartburn, changes in bowel habits, weight loss, problems with swallowing, nausea and vomiting. These symptoms will be discovered through the administration of a questionnaire.
