I recently underwent an attempted ablation at one of the UK's most famous cardiac hospitals. The insertion of the catheter went well and the EP managed to get it into the right atrium. However he had to abandon the procedure because he found my right atrium was enlarged and he could not navigate the catheter through to the OS and into my left atrium to reach the necessary place to allow ablation to take place. Instead he did a cardioversion which did stop my AF for a whole day! He initially said that ablation of the AV node was an alternative option, but when I visited him a month later he dismissed this saying it would not have any effect on my now persistent AF- a view confirmed by my cardiologist-but no real explanation has been offered for this and I am now somewhat confused, and feel I'm being fobbed off. Any one who has had a similar experience may be able to advise.
