Mayo Clinic has clinics in Arizona. I'd try them.
I see that you live in New Mexico. Your best bet is to go to Austin, Texas and see Dr. Natale. He is considered on of the best for ablations. He originally was at Cleveland Clinic and now is in Texas. If I were you I wouldn't look anywhere else. Like I said he is the best.
Well if you're willing to travel hospitals such as the Cleveland Clinic are recognized worldwide for their delivery of heart surgery and other procedures, such as ablations. There are many others.
Look for the nearest hospital that has a full-service heart facility, i.e., does surgery. Then look at the doctors that practice there and find one that specializes in ablations, maybe even in the specific ablation you need.
I had open heart surgery at a smaller heart center, Doylestown Heart Institute and went there because my research said the director of surgery, my surgeon, was very experienced, yet young and had a great success record.
