I've mentioned FIRM ablations before as they have a good success rate. This independent trial has just been published:
after a single procedure, 87.5% of patients who had not previously had an ablation were free of AF after 1 year. That's a remarkably good result - much better than the average 50% or so achieved currently. Also the majority of patients were persistent, who have always been more difficult to ablate. Additionally the technique appears relatively easy for EP's to learn and get consistently good results.
This study was carried out in the US. It would be good if someone could do it in the UK.
If I were looking for an ablation (which I'm not, having had a successful one 4 years ago), I would seriously look at having this technique and even holding off until it was available.
