Try Brett Gidney, Santa Barbara. I agree, you want the best for this. Check him out, he fixed my problem, and is extremely experienced.
You didn't mention what type of ablation you need. For AF, Natale still goes to SF from his base in Texas. No doubt he is the top gun if you can get an appt. If it is AF, the moderator at afib.org blog knows him well and can probably help get your foot in the door. Best wishes to you.
