Brief summary

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.

Interventions

DEVICEVARIPULSE Catheter System

Pulsed field ablation by VARIPULSE Catheter System (VARIPULSE bi-directional catheter and TRUPULSE generator) will be used.

DEVICELAAO Device

LAAO procedures will be performed using commercially available LAAO devices in accordance with the device's instruction for use (IFU).

Inclusion criteria

* 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

Exclusion criteria

* Participant has continuous AF \> 365 days (longstanding persistent AF) * Participant has AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause (for example, untreated documented obstructive sleep apnea, acute alcohol toxicity, etc.) * Participant has had previous surgical or catheter ablation for AF * Participant is known to require ablation outside the left atrium (LA), superior vena cava (SVC), and the cavotricuspid isthmus (CTI) region (for example, atrioventricular reentrant tachycardia, atrioventricular nodal reentry tachycardia, ventricular tachycardia and Wolff-Parkinson-White) * Participant has LA (left atrial) anteroposterior \>= 55 millimeter (mm) (by magnetic resonance imaging \[MRI\], computed tomography \[CT\], or transthoracic echocardiogram \[TTE\]), or if LA diameter is not available, non-index volume \>100 milliliter (mL) confirmed within 365 days prior to enrollment * Participant has LA thrombus confirmed by imaging within 48 hours prior to the procedure * Participant has severely compromised left ventricular ejection fraction (left ventricle ejection fraction \[LVEF\] less than \[\<\] 40 percent \[%\]) confirmed by imaging performed within 180 days prior to enrollment * Participant has uncontrolled heart failure or New York heart association (NYHA) Class III or IV functional classification * Participant has a history of blood clotting, bleeding abnormalities or contraindication to anticoagulation (for example, heparin) * Participant has had a thromboembolic event (including transient ischemic attack \[TIA\]) within the past 180 days prior to enrollment * Participant has had a percutaneous coronary intervention or acute myocardial infarction (MI) within past 60 days prior to enrollment * Participant has had coronary artery bypass grafting (CABG) surgery within the past 180 days prior to enrollment * Participant has had valvular cardiac surgical/percutaneous procedure (that is, ventriculotomy, atriotomy, valve repair or replacement and presence of a prosthetic valve) * Participant has unstable angina within past 6 months prior to enrollment * Participant has anticipated cardiac transplantation, cardiac surgery, or other major surgery within the next 365 days post-procedure * Participant has significant pulmonary disease (for example, restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces severe chronic symptoms * Participant has a significant congenital anomaly (for example, atrial septal defects \[ASDs\]) including repaired defects or medical problems that in the opinion of the Investigator would preclude enrollment in this study * Participant has an existing diagnosis of pulmonary vein stenosis (PVS) * Participant has a pre-existing hemi-diaphragmatic paralysis * Participant has an acute illness, active systemic infection, or sepsis * Participant has an intracardiac thrombus, myxoma, tumor, interatrial baffle or patch or other abnormality that precludes catheter introduction or manipulation * Participant has severe mitral regurgitation (Regurgitant volume greater than or equal to \[\>=\] 60 milliliters \[mL\]/beat, Regurgitant fraction \>= 50%, and/or Effective regurgitant orifice area \>= 0.40 square centimeter \[cm\^2\]) * Participants with an implanted metal cardiac device that may interfere with the pulsed field energy field are excluded, including but not limited to: -MitraClip, -LAAO devices (for example, WATCHMAN, Amulet), -Double-coiled implantable cardioverter-defibrillators (ICDs).

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants with Early Onset Primary Adverse Events (PAEs)Up to approximately 7 days post-procedurePAEs include early onset AEs such as esophageal perforating complications, phrenic nerve paralysis (PNP; permanent), cardiac tamponade/perforation, pulmonary vein stenosis (PVS), death (device or procedure related), stroke/ cerebrovascular accident (CVA), major vascular access, complication/bleeding, thromboembolism, myocardial Infarction (MI), transient ischemic attack (TIA), pericarditis, pulmonary edema (respiratory insufficiency), heart block, and vagal nerve injury/ gastroparesis.
Freedom from Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmia EpisodesDay 61 up to Day 180Number of participants reporting freedom from documented (symptomatic and asymptomatic) atrial tachyarrhythmia (that is, atrial fibrillation or atrial tachycardia or atrial flutter \[AF, AT or AFL\] of unknown origin) episodes based on electrocardiographic data and freedom from acute procedural failure, repeat ablation failure, surgical treatment for AF/AT/AFL, non-study catheter (NSC) failure, antiarrhythmic drug (AAD) failure and any direct current (DC) cardioversion procedure.

Secondary

MeasureTime frameDescription
Freedom from Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmia EpisodesDay 61 up to Day 365Number of participants reporting freedom from documented (symptomatic and asymptomatic) atrial tachyarrhythmia (that is, AF, AT or AFL of unknown origin) episodes based on electrocardiographic and freedom from acute procedural failure, repeat ablation failure, surgical treatment for AF/AT/AFL, NSC failure, AAD failure and any DC cardioversion (DCCV) procedure.
Change From Baseline in Quality of life, As Measured by the Total Atrial Fibrillation Effect on Quality-of-Life (AFEQT) ScoreBaseline, at 12 months post-procedureThe AFEQT uses a questionnaire to evaluate symptoms, daily activities and treatment concerns participants have related to atrial fibrillation. An overall AFEQT score ranges from 0 to 100. A score of 0 corresponds to complete disability (or responding "extremely" difficult to all questions answered), while a score of 100 corresponds to no disability (or responding "not at all" limited, difficult or bothersome to all questions answered). A positive change in score corresponds to improvement in AF symptoms.
