It would be interesting to hear, when people talk about their ablations, whether they had RF., or Cryo Ablations and also which type of Ablation people have, ie., PVI Ablation or other types of Ablations. I also see that many people are saying that they have had 1,2 or 3 Ablations! If its PVI Ablation then I presume rightly or wrongly that the reason for more than 1 Ablation is because the procedure didn't cause a complete 360 degree burn of the cells, therefore requiring further Ablations after the scar tissue has healed. I don't know if anyone has seen the Sky News video on The London Heart Hospitals website about the Laser Ablation procedure that was first carried out in August 2011, by a Doctor Segal, very interesting video, well worth a look. Apparently they use a catheter that has a camera so they can visualize all the structures on real time video and also use a Laser with a Balloon to cause the burn. They say its got a 90%+ success rate for a first time Ablation, problem is as of this moment as far as I'm aware London is the only place that has this latest equipment in the UK., Dr. Segal says in the video, that because of the better rate of one time Ablation success, it has to be cost effective to the NHS. He also says that he hopes it will be rolled out across the NHS., at all the major heart centres in England and Wales, but as there's London and then there's the rest of the UK., only time will tell if any other hospitals will have this new technology in the future.
