Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is designed as a prospective, multicenter, single-blind, randomized study to assess the safety and effectiveness of FIRM-guided radiofrequency (RF) ablation procedures for the treatment of symptomatic paroxysmal atrial fibrillation (PAF). The subjects will be blinded to study treatment for the duration of the study period.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Experiencing at least two (2) documented episodes of paroxysmal atrial fibrillation in the last 3 months preceding study entry with clinical indication for atrial fibrillation (AF) ablation per guidelines. At least one episode should be documented by rhythm strip or ECG.
* Indicated for AF ablation according to current European Heart Rhythm Association (EHRA) guidelines.
* Prescribed with oral anticoagulation therapy, in indicated patients per the latest EHRA guidelines.
* Willingness and able to remain on anti-coagulation therapy as per the latest EHRA guidelines.
* Left atrial diameter \< 5.5 cm as measured and image ((computed tomography (CT)/ transesophageal echocardiogram (TEE)/ transthoracic echocardiogram (TTE)/ magnetic resonance imaging (MRI) or intracardiac echocardiography (ICE)) documented within previous six months up to pre-procedure.
* Sustained AF (\>5 min uninterrupted) during the electrophysiology procedure. If the subject is not experiencing spontaneous, sustained AF, it may be induced by burst pacing (typically from the coronary sinus) with or without isoproterenol infusion in conventional clinical fashion.

Exclusion Criteria

* New York Heart Association heart failure (NYHA) Class III - IV.
* Ejection fraction \< 40% (within previous six months).
* History of myocardial infarction (MI) within the past three months.
* Any concomitant arrhythmia or therapy that could interfere with the interpretation of the results from this study.
* Atrial septal defect (ASD) closure device, left atrial appendage (LAA) closure device, prosthetic mitral or tricuspid valve, or permanent pacemaker.
* Any previous AF catheter ablation.
* History of prior cardioversion for AF lasting \> 48 hours.
* Continuous AF episode lasting \> 7 days immediately prior to the procedure without a sinus rhythm.
