Assessment of the Safety and Effectiveness of the VARIPULSE™ Catheter System in the Treatment of Participants With Persistent Atrial Fibrillation Undergoing Pulmonary Vein (With or Without Posterior Wall Isolation) and Superior Vena Cava Isolation: A Randomized Controlled Trial
The purpose of this study is to assess how safe VARIPULSE catheter system is for treatment of a heart rhythm disease called persistent atrial fibrillation (PsAF) in participants who are having a catheter ablation procedure (treat heart rhythm disease). This includes isolation of pulmonary vein and superior vena cava (heart veins; pulmonary vein isolation \[PVI\] and superior vena cava isolation \[SVCI\]), with or without another technique called posterior wall isolation (PWI). Also, to assess how safe it is for participants who are having a catheter ablation procedure and at the same time receiving another procedure called left atrial appendage occlusion (LAAO; to reduce stroke risk). Additionally, to assess how well VARIPULSE catheter system works over a long period of time for treatment of PsAF in participants undergoing catheter ablation for PVI, SVCI and SVCI+PWI.
• Participant has been diagnosed with symptomatic persistent atrial fibrillation (PsAF), which is defined as continuous atrial fibrillation (AF) sustained beyond 7 days in duration and less than 365 days in duration, documented by: i. A physician's note documenting diagnosis of symptomatic PsAF, as defined above; and ii. Two electrocardiograms (ECGs) showing continuous AF, with electrocardiogram taken at least 7 days apart (electrocardiograms cannot be greater than (\>) 365 days prior to enrollment); or iii. A 24-hour arrhythmia monitor documenting continuous AF within the last 365 days
• Participant is aged 18 - 80 years at the time of informed consent
• Participant is willing and capable of providing informed consent
• Participant is able and willing to comply with all pre-, post- and follow-up testing and requirement
⁃ Left atrial appendage occlusion (LAAO) concomitant subset:
⁃ \- Participant is clinically indicated for a LAAO procedure
