Yes, such questions are/ought to be allowed because they help put troubled, deeply anxious, and needy people in touch with experts who can possibly help them.
I know of two EPs who are world class, or know of them, but have no experience with them. The first, widely touted over on the free forum site afibbers.org, is Dr. Andrea Natale at the Texas Cardiac Arrhythmia Institute in Austin. He travels to several hospitals in the American west, including La Jolla and Los Robles. He gets patients from all over who learn of his skills and record of success. I know less about Dr. Pasquale Santangeli at Cleveland Clinic, but he has an enviable reputation. The only other leader in the field that I know of, and he trained Natale, is Dr. Pierre Jais in Bordeaux, France. He also treats international patients.

Well, I just learned that Mayo Clinic does not accept any Medicare Advantage plan so that rules me out.
