Adjunctive Right Atrial Ablation for Persistent Atrial Fibrillation With Right Atrial Enlargement
研究概览
地位
详细说明
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.

干预/治疗 |
|---|---|
|
LA + RA ablation
Patients with persistent atrial fibrillation and right atrial enlargement received adjunctive right atrial ablation when left atrial ablation did not terminate atrial fibrillation.
|
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
