Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study it to learn whether pulmonary vein isolation (PVI) along with isolation of the posterior left atrial wall (PWI) in the region of the pulmonary venous component will reduce the likelihood of atrial fibrillation (AF) recurrence in patients with persistent atrial fibrillation at 12 months, after a single ablation procedure, in comparison to PVI alone. The investigator hypothesizes that the combination of PVI + PWI will result in a significant reduction in recurrence of atrial fibrillation at 12 months after ablation.
