Number of Participants Experiencing Recurrence of Atrial Fibrillation by One Year Follow-up [ Time Frame: 12 months after intervention ]
Documentation of atrial fibrillation using a cardiac event recorder
Percutaneous left atrial catheter ablation for the purpose of eliminating AF is superior to current state-of-the-art therapy with either rate or rhythm control drugs for reducing total mortality in patients with untreated or under-treated AF. [ Time Frame: Trial length ]

Ablation vs Drug Therapy for Atrial Fibrillation - Pilot Trial
Catheter Ablation Versus Antiarrhythmic Drug Therapy for Atrial Fibrillation - Pilot Trial
The CABANA pilot study is designed to test the hypothesis that the treatment strategy of percutaneous left atrial catheter ablation for the purpose of the elimination of atrial fibrillation (AF) is superior to current state-of-the-art therapy with either rate control or anti-arrhythmic drugs for reducing AF recurrences at 1 year follow-up.
The need for this trial arises out of 1) the rapidly increasing number of pts > 60 years of age with AF accompanied by symptoms and morbidity, 2) the failure of anti-arrhythmic drug therapy to maintain sinus rhythm and reduce mortality, 3) the rapidly increasing application of radio-frequency catheter ablation without appropriate evidence-based validation, and 4) the expanding impact of AF on health care costs.

  • Active Comparator: Pharmacologic Therapy
    Pharmacologic Therapy Rate and/or Sinus Rhythm Control: Patients without other heart disease will receive beta or calcium channel blockers as first line rate control therapy. Patients with underlying coronary artery disease will receive beta-blockers, patients with limited ventricular hypertrophy not warranting exclusion would receive either beta- or calcium channel blockers, while patients with heart failure would be expected to receive carvedilol or metoprolol. Patients randomized to drug therapy may be started on a membrane active drug, in an approach consistent with the recommended Guidelines for Management of Subjects with AF. Each patient will be placed on an anti-arrhythmic drug for an appropriate period and the patient cardioverted to sinus rhythm if necessary. Patients will then be followed for a period of up to 3 months, during which dosage adjustment can be made or the drug replaced with a different anti-arrhythmic drug.
