Predictors of recurrence after catheter ablation of persistent atrial fibrillation include advancing age, longer AF duration, structural heart disease, and left atrial enlargement.
Identifying clinical and anatomical predictors of recurrence can help optimize patient selection and ablation strategies for persistent atrial fibrillation.
Radiofrequency catheter ablation that targets the pulmonary veins is well established as a mainstay for drug-refractory, paroxysmal atrial fibrillation (AF). However, in patients with persistent AF, the ideal approach remains elusive. Further, despite the various additional ablation strategies that have been investigated in patients with persistent AF, the rate of recurrent atrial tachyarrhythmias after ablation remains relatively high. In this review, the predictors of recurrent atrial tachyarrhythmias after catheter ablation of persistent AF will be discussed.
Yokokawa et al. (Sat,) conducted a review in Persistent Atrial Fibrillation. Radiofrequency catheter ablation was evaluated. Predictors of recurrence after catheter ablation of persistent atrial fibrillation include advancing age, longer AF duration, structural heart disease, and left atrial enlargement.
