Pulmonary vein isolation (PVI)-only is not enough for all patients with persistent atrial fibrillation (AF): A FLOW-AF subgroup analysis
Authors' conclusion
Success rates in no-sources patients receiving PVI only are better than in those with sources randomized to PVI only.
Study context
- Population
- Patients with nonparoxysmal (persistent/longstanding persistent) AF undergoing redo ablationof 85 enrolled
