Live discussion and demonstration of the atrial fibrillation ablation. Complete atrial fibrillation using cryoballoon ablation second generation Arctic Front Advance. High-lighting the use of minimal fluoroscopy x-ray exposure by using intracardiac ultrasound and 3-dimensional mapping. Additional atrial flutter line was also performed. Full discussion with experienced atrial fibrillation ablation physicians and cryoballoon users. Not a straight-forward case– good learning points for the best practice of atrial fibrillation ablation and avoidance of complication.
