In the prospective, single-arm, open-label, multi-center NAVIGATE-PF study, approximately 30 patients at several European centers who live with paroxysmal or persistent AF will be enrolled. All patients in the study will have cardiac mapping performed during their procedures. Those living with paroxysmal AF will undergo pulmonary vein isolation, while patients with persistent AF will undergo additional posterior wall isolation at the discretion of the physician performing the procedure.
