There is a new way of mapping where the AF sites are, and it is available in UK. The machine was a long time coming here because it had to be given some safety mark. I contacted one of the Drs on the team, and through him another cardioloigist in Addenbrookes who Im seeing again in December for a discussion with view to having this done. I don't know where else it may be available but hope its of use to someone.
From my discussions so far, my understanding is it doesn't reduce the total time in theatre, but does reduce the burn time as well as improve accuracy and success rate. Cardio told me theres newer things coming in all the time and there may be a better one for me if I waited a little, hence seeing him soon for final chat.
