Arrhythmias & electrophysiologyCohort study
Repeat catheter ablation after very late recurrence of atrial fibrillation after pulmonary vein isolation
- Prospective registry cohort study
- Swiss
Authors' conclusion
There was no association between the time to recurrence of AF after initial CA and the characteristics and outcomes of the repeat procedure.
Study context
- Population
- Patients undergoing a first repeat atrial fibrillation (AF) catheter ablation after index pulmonary vein isolation, Swiss prospective registryof 1864 in registry
- Participants

- Freedom from AF
- Follow-up
- First year after repeat ablation
