Overview
Brief Summary
This is retrospective cohort study testing whether patients with persistent atrial fibrillation and right atrial enlargement may benefit from adjunctive right atrial ablation.
Detailed Description
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.
