I had an cryo ablation 3 days ago at Whipps Cross hospital London .Excellent team, had sedation didn't feel anything, only small bruise. I used to be in AF about every 3 wks for about 17 hrs just taking warfarin, I will have to wait a couple of wks to find out if it has been successful, the Dr seemed to think it had gone well.It was hard for me to be a patient as I was a cardiac technician in a cath lab 30 yrs ago!! but great advances in equipment. They warned me of physical complications but not the mental effects of the morphine and other sedation drugs . This may just be me but have had a low irritable mood which is just lifting but a small price to pay if it has got rid of the AF. Just hoping that it has !
