I had AFIB for 18 months that after 1 year it became basically out of control in spite of taking 3 expensive medications that sapped my energy - and had CardioVersions. I spoke to my smaller town (100k pop) surgeon his success Ablation Surgery rate? 40%!! So after checking a few other Doctors out of town I went to Mayo Clinic Phoenix and had the surgery 11/20. I have not had an AFIB experience since and I am 77 years old. I only take Eliquis now because I have a history of blood clots. Just saying.
