The main purpose of this study is to investigate the workflow of the clinical use of the pulsed field (PF) ablation system (VARIPULSE catheter and TRUPULSE generator) when used for cardiac ablation with the new VARIPULSE Pro software in participants with persistent atrial fibrillation (PsAF; irregular, rapid heart rhythm that lasts over 7 days and doesn't stop on its own).
Diagnosed with symptomatic persistent atrial fibrillation (PsAF)
Selected to undergo an ablation procedure for management of their arrhythmia by pulmonary vein isolation (PVI) +
Failed at least one antiarrhythmic drug (AAD; class I to IV) as evidenced by recurrent symptomatic atrial fibrillation (AF), or intolerable or contraindicated to the AAD
Age 18-75 years
Continuous AF greater than (>) 12 months (1-Year) (Longstanding Persistent AF)
Previous surgical or catheter ablation for atrial fibrillation
Any cardiac surgery within the past 2 months (60 days prior to consent date) (includes percutaneous coronary intervention [PCI])
Previous coronary artery bypass grafting (CABG) in conjunction with valvular surgery, cardiac surgery (for example, ventriculotomy, atriotomy) or valvular cardiac (surgical or percutaneous) procedure
