Vagus Nerve Injury Post Radiofrequency Catheter Ablation for Atrial Fibrillation

Vagus Nerve Injury Post Radiofrequency Catheter Ablation for Atrial Fibrillation (Vagus Nerve Study)

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.

Inclusion Criteria:

• Patients with a verified medical history of atrial fibrillation.
• Male or female >18 years of age.
• Patients scheduled for an RFCA procedure, subsequent to failure of one Antiarrhythmic Drug (AAD class I, III or IV), or ablation.
• Ability to answer questions posed by the questionnaire.
• Ability to understand and sign a written informed consent form, which must be obtained prior to initiation of any study procedures.

Exclusion Criteria:

• None
