This is retrospective cohort study testing whether patients with persistent atrial fibrillation and right atrial enlargement may benefit from adjunctive right atrial ablation.
This is retrospective cohort study testing whether patients with persistent atrial fibrillation and right atrial enlargement may benefit from adjunctive RA ablation. 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.

OBSERVATIONAL
Enrollment
195
Patients receive circumferential pulmonary vein isolation and linear ablation (ablation of a roof line and a mitral isthmus line) combined with bi-atrial mapping and left atrial driver ablation.

atrial fibrillation (AF) recurrence rate
AF recurrence is defined as presence of documented AF episodes of 30 seconds or longer duration
Time frame: at 12 months post procedure
atrial fibrillation (AF)/atrial flutter (AFL)/atrial tachycardia (AT) recurrence rate
AF/AFL/AT recurrence is defined as presence of documented AF/AFL/AT episodes of 30 seconds or longer duration
Time frame: at 12 months post procedure
