NCT01095770

Brief Summary

The purpose of this study is 3 fold:-

  1. 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. 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. 3.To accurately evaluate, by continuous rhythm monitoring for 1 year, the efficacy of AF ablation therapy for PAF.

Outcome Measures

Primary Outcomes (3)

  • AF Burden

    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.

    12 Months

  • AF Burden

    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.

    12 months

  • AF Burden detected

    To evaluate the Reveal XT ILR as a long term accurate AF monitoring device as compared to the 'gold standard' DDD pacemaker Holter.

    12 months

Secondary Outcomes (5)

  • Arrhythmia frequency - symptomatic or asymptomatic.

    12 months

  • Time to first episode of AF

    12 months

  • Average AF duration

    12 months

  • Time to persistent AF.

    12 months

  • Average SR duration.

    12 months
