Implication

Staged biatrial ablation may restore sinus rhythm in refractory chronic AF; leaves open efficacy and safety in controlled trials.

Key Points

To evaluate the effectiveness of a two-staged biatrial linear and focal radiofrequency ablation procedure for restoring normal sinus rhythm in patients with chronic atrial fibrillation.
Described clinical experience with two-staged biatrial linear and focal radiofrequency ablation (BALF I, II) procedures.
Confirmed drug refractoriness and optimized anticoagulation prior to intervention.
Utilized transesophageal echocardiography to exclude thrombus and performed extensive left atrial mapping and ablation.
Of the 11 patients with late follow-up data, 9 achieved normal sinus rhythm and no longer experienced chronic atrial fibrillation.
Localized electrogram recordings identified rapid, localized focal driving rotors in the left atrium in nine patients and in the right atrium in one patient.
No thromboembolic complications occurred, though two patients experienced pericardial tamponade managed medically.

Structured PICO

Does two-staged biatrial linear and focal radiofrequency ablation restore normal sinus rhythm in patients with refractory chronic atrial fibrillation?

Population

Patients with refractory chronic atrial fibrillation (CAF), n=11 with late follow-up data.

Intervention

Two-staged biatrial linear and focal radiofrequency ablation (BALF I, II)

Outcome

Restoration of normal sinus rhythm (NSR)

A two-staged biatrial linear and focal radiofrequency ablation procedure successfully restored normal sinus rhythm in 9 out of 11 patients with refractory chronic atrial fibrillation at >1 year follow-up.
