  Purpose

The purpose of this study is 3 fold:-

  1. To compare the efficacy and complication rates of 2 widely used methods, conventional irrigation tip ablation catheter (LASSO) and Ablation Frontiers ablation technology, of AF ablation for PAF.
  2. To evaluate the Reveal XT ILR as a long term accurate AF monitoring device as compared to the 'gold standard' DDD pacemaker Holter.
  3. To accurately evaluate, by continuous rhythm monitoring for 1 year, the efficacy of AF ablation therapy for PAF.

Primary Outcome Measures:
  • AF Burden [ Time Frame: 12 Months ]
    AF Burden post left atrial ablation is defined as the sum of the duration of all atrial tachyarrhythmias expressed as a percentage of the total observation period as assessed by PM Holters.

  • AF Burden [ Time Frame: 12 months ]
    Comparison of AF burden post PVI ablation using a conventional irrigation tip catheter with LASSO guidance (or equivalent) versus Ablation Frontiers Technology using the PVAC, MASC and TVAC catheters via standard trans-septal techniques.

  • AF Burden detected [ Time Frame: 12 months ]
    To evaluate the Reveal XT ILR as a long term accurate AF monitoring device as compared to the 'gold standard' DDD pacemaker Holter.


Secondary Outcome Measures:
  • Arrhythmia frequency - symptomatic or asymptomatic. [ Time Frame: 12 months ]
    Arrhythmia Frequency is defined as the total number of atrial tachyarrhythmic episodes divided by the observation period, expressed as episodes per day as assessed by PM Holters.

  • Time to first episode of AF [ Time Frame: 12 months ]
    Time to persistent AF is defined as the time from ablation to the first recorded episode of AF

  • Average AF duration [ Time Frame: 12 months ]
    Average arrhythmia duration is defined as the total duration of atrial arrhythmia divided by the total number of atrial arrhythmia episodes.

  • Time to persistent AF. [ Time Frame: 12 months ]
    Time to persistent AF (atrial fibrillation episode lasting for 7 days)

  • Average SR duration. [ Time Frame: 12 months ]
    Average sinus rhythm duration is defined as the total duration of sinus rhythm from first atrial arrhythmic episode until last atrial arrhythmic episode divided by the number of atrial arrhythmic episodes minus 1.
