The New Pharmaceutical Composition Containing Botulinum Toxin to Treat Atrial Fibrillation

Injection of the New Pharmaceutical Composition Containing Botulinum Toxin Into Epicardial Fat Pads to Treat Atrial Fibrillation After Coronary Artery Bypass Grafting

The aim of this prospective randomized double-blind study was to compare the efficacy of new pharmaceutical composition containing botulinum toxin injection in epicardial fat pads for preventing recurrences of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass grafting.

Inclusion Criteria:

• Patients with paroxysmal AF (recurrent episodes for at least 2 years, with ≥ 6 episodes over the last 6 months)
• At least one failed antiarrhythmic drug
• Indication for cardiac surgery (e.g. coronary artery bypass grafting, valve repair/replacement) according to the American College of Cardiology/American Heart Association (ACC/AHA) guidelines for cardiac surgery

Exclusion Criteria:

Previous heart surgery or atrial fibrillation ablation procedure Emergency coronary artery bypass grafting Unstable angina or heart failure Persistent atrial fibrillation or atrial fibrillation at the time of screening Planned maze procedure or pulmonary vein isolation Unwillingness to participate
