The mini-maze
in the left atrium is specific to
AF treatment. That said, I had a mini-maze done
in Nov. 2007 when my Mitral Valve was repaired (luck me, it was repaired with a simple ring installed to limit the size of the opening). It did not cure my AFib... I was in NSR for about 30 days, then back to permanent AFib.
I'm not too happy about beta blockers either, they don't give me a headache, but I do have a lot of trouble dreams (trouble-mares) that may be related to the BB.
