Follow-Up
There were no procedure-related complications. All 8 patients were in sinus rhythm after ablation. Despite high-rate pacing, 6 of them were noninducible; atypical nonsustained flutter was inducible in 1, and AF was inducible in 1. A pacemaker was implanted in 1 patient due to sinus bradycardia 3 days after ablation. With a mean follow-up of 12 months, all 7 patients were successfully treated with no antiarrhythmic drugs. LA flutter reoccurred in 1 patient 1 week after ablation.
