Impact of Medical Treatment on Long-Term Results after Surgical Ablation of Atrial Fibrillation in Cardiac Surgical Patients

Abstract

AF treatment with HIFU ablation during concomitant cardiac surgery is a safe and effective procedure for restoring SR, especially in patients with AF and especially in patients with a smaller left atrial diameter. No significant difference was noted between the antiarrhythmic and non drug groups regarding restoration and maintaining SR; however, better results were achieved by those taking a β-blocker.
