Brief Summary:
The aim of the study is to compare the acute procedure and safety outcomes as well as long term clinical outcomes of 2 groups of patients treated with the HeartLight® Endoscopically Guided Laser Ablation (EGLA) or a commercially available Contact Force Sensing Irrigated Radiofrequency (RF) Ablation Catheter plus, at the operator's discretion, 3D Electroanatomical Mapping (EAM) for the treatment of Paroxysmal Atrial Fibrillation (PAF).

Arm Intervention/treatment
Active Comparator: HeartLight® EGLA
Participants will be treated with the endoscopically guided laser ablation catheter
Device: Ablation catheter
Ablation of paroxysmal atrial fibrillation

Active Comparator: Contact Force Sensing Irrigated RF ablation
Participants will be treated with a contact force sensing irrigated radiofrequency ablation catheter
Device: Ablation catheter
Ablation of paroxysmal atrial fibrillation




Primary Outcome Measures :
  1. Freedom from symptomatic, recurrent atrial fibrillation (AF) off of anti-arrhythmic drugs [ Time Frame: 12 months post procedure ]
    Recurrent AF is defined as any documented episode of AF lasting more than 30 seconds after a blanking period of 90 days post procedure


Secondary Outcome Measures :
  1. Acute procedure success [ Time Frame: 30 minutes post procedure ]
    Confirmation of electrical isolation with a circular mapping catheter

  2. Procedure and fluoroscopy time [ Time Frame: During procedure ]
    Time will be taken

  3. Incidence of peri-procedural complications [ Time Frame: From procedure to 12 months post procedure ]
    E.g. major bleeding requiring intervention, phrenic nerve palsy, pericardial tamponade, thrombo-embolic events, pulmonary vein (PV) -stenosis, atrial-to-esophageal fistula, death

  4. Freedom from symptomatic, recurrent Atrial Tachy Arrhythmia (ATA) off of anti-arrhythmic drugs [ Time Frame: 12 months post procedure ]
    Recurrent ATA is defined as any documented episode of ATA lasting more than 30 seconds after a blanking period of 90 days post procedure

Criteria

Inclusion Criteria:

  • Patient must not have undergone a previous ablation for the treatment of PAF
  • AF Type - Diagnosed with symptomatic paroxysmal atrial fibrillation (PAF) where PAF is defined as recurrent (two or more) episodes of AF that terminate spontaneously in less than seven days, usually less than 48 hours

Exclusion Criteria:

  • Atrial fibrillation secondary to a reversible cause or of non-cardiac origin
  • Diagnosed with persistent atrial fibrillation defined as recurrent episodes lasting more than 7 and less than 365 days
  • More than 4 electrical cardioversions in the year prior to enrollment but not including cardioversions performed within 48 hours of arrhythmia onset
  • Documented left atrial thrombus on imaging
  • Cannot be removed from anti-arrhythmic drugs for other reasons than atrial fibrillation
  • New York Heart Association (NYHA) functional Class III or Class IV heart failure
  • Left ventricular ejection fraction < 30%
  • Left atrial size > 55 mm as measured in the parasternal antero-posterior view
  • Myocardial infarction within 60 days prior to enrolment
  • Woman of childbearing potential who is pregnant, lactating or not using adequate birth control
