ablationist/ep in Columbia, SC

Has anyone had any experience with Dr. Walter Mazzei in Columbia, SC? Had an ablation with Dr. Marcus Wharton in '08 and it was successful, but it has returned. Possibly Flecainide will take care of this, but Dr. Wharton has a long waiting list. Some locals think Dr. Mazzei can get the job done. Just looking for more info. Thanks for anyone who might know something...
