Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
We enrolled 65 patients with persistent atrial fibrillation and right atrial enlargement received adjunctive right atrial ablation. These patients were 1:2 match with 130 patients received left atrial ablation only. Atrial fibrillation recurrence rate and other paremeters were analyzed to evaluate the efficacy of adjunctive right atrial ablation in this subset of patients.

Circumferential pulmonary vein isolation + linear ablation + bi-atrial mapping + left atrial driver ablation + right atrial driver ablation
Patients receive circumferential pulmonary vein isolation and linear ablation (ablation of a roof line and a mitral isthmus line) combined with bi-atrial mapping , left atrial driver ablation and right atrial driver ablation.
LA ablation only
Patients with persistent atrial fibrillation and right atrial enlargement received left atrial ablation only
Circumferential pulmonary vein isolation + linear ablation + bi-atrial mapping + left atrial driver ablation
