Key result
Ablation of rotor domains effectively decreased atrial activation frequency (P<0.05), with 70% of patients with long-standing persistent atrial fibrillation remaining in sinus rhythm at 1 year.
Why the study?
Does ablation of rotor domains decrease the frequency of activation and improve rhythm outcomes in patients with long-standing persistent atrial fibrillation?
Does ablation of rotor domains decrease the frequency of activation and improve rhythm outcomes in patients with long-standing persistent atrial fibrillation?
Ablation of rotor domains in long-standing persistent atrial fibrillation effectively modifies atrial dynamics by decreasing activation frequency, which may support the maintenance of sinus rhythm.

Rotor mapping in persistent AF remains investigational; this small series leaves open questions on clinical utility and requires randomized validation.
Calvo et al. (2017) studied long-standing persistent atrial fibrillation (n=13). Ablation of rotor domains vs. Ablation of nonrotor domains was evaluated on Sinus rhythm at 1-year follow-up. Ablation of rotor domains effectively decreased atrial activation frequency (P<0.05), with 70% of patients with long-standing persistent atrial fibrillation remaining in sinus rhythm at 1 year.
