RFA eliminated all focal and ultimately reentrant ATs in 15 of the 32 patients; RFA was required at the right atrial (RA) projections of BB among eight of the latter patients. The electrogram at the successful site was devoid of local voltage in four patients. In nine patients with redo procedure, recurrent BB\u2010AT was found in five (56%).
