Left Atrial Ablation With Permanent Pacemaker or ImplanTable Loop Recorder Follow-UP (LAAPITUP)
The purpose of this study is 3 fold:-
- 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.
- To evaluate the Reveal XT ILR as a long term accurate AF monitoring device as compared to the 'gold standard' DDD pacemaker Holter.
- To accurately evaluate, by continuous rhythm monitoring for 1 year, the efficacy of AF ablation therapy for PAF.
