What is Atrial Fibrillation Ablation?
Atrial fibrillation ablation is a catheter procedure that isolates or modifies the electrical triggers of AF, most often around the pulmonary veins, to reduce AF burden in selected patients. Catheters enter the heart from the veins. After transseptal access, a mapping system guides pulmonary-vein isolation using radiofrequency, cryoballoon or another energy source selected by the electrophysiologist.
