Key result
Catheter ablation maintains AF freedom for >3 years, though multiple procedures are often required.
Why the study?
Does catheter ablation prevent long-term recurrence in patients with atrial fibrillation?
Does catheter ablation prevent long-term recurrence in patients with atrial fibrillation?
Catheter ablation is an effective long-term treatment for atrial fibrillation, particularly for paroxysmal AF, though repeat procedures may be necessary to maintain sinus rhythm.
May support ablation consideration for durable paroxysmal AF control; leaves open optimal strategies and RCT confirmation.
Catheter ablation -in general- is a highly effective and "curative" intervention for a broad spectrum of supraventricular and ventricular arrhythmias. After a successful procedure eliminating a simple arrhythmia substrate, the recurrence rate is low and the short term success correlates well with the long term freedom from the arrhythmia.

Tutuianu et al. (2015) conducted a review in Atrial Fibrillation. Catheter ablation was evaluated on Long-term freedom from atrial fibrillation. Catheter ablation provides maintainable long-term freedom from atrial fibrillation over 3 or more years, particularly for paroxysmal AF, though multiple procedures are often required.
