Short- and long-term efficacy and safety of catheter ablation versus antiarrhythmic drugs for atrial fibrillation: a meta-analysis of randomized trials
Longer duration of persistent atrial fibrillation episodes prior to catheter ablation is associated with lower freedom of atrial arrhythmias after catheter ablation
Identification of predictors for atrial fibrillation-free survival after catheter ablation of persistent atrial fibrillation-results from a large prospective cohort
