Why the study?
Prior studies have described diverse AF mechanisms originating in the RA, prompting the report of a patient series where an extensive right atrial free wall low-voltage zone served as the AF substrate.
Does radiofrequency ablation targeting the right atrial free wall low-voltage zone eliminate atrial fibrillation in patients with this specific substrate?

May support right atrial low-voltage zone ablation for AF in this rare substrate; hypothesis-generating and requires prospective validation before practice change.
Does radiofrequency ablation targeting the right atrial free wall low-voltage zone eliminate atrial fibrillation in patients with this specific substrate?
Radiofrequency ablation targeting extensive low-voltage zones in the right atrial free wall is an effective strategy for managing AF and AT in patients with this unusual substrate.
