Catheter Ablation As Treatment For Atrial Fibrillation

Atrial fibrillation frequently arises from an abnormal focus at or near the junction of the pulmonary veins and the left atrium, thus leading to the feasibility of more focused ablation techniques directed at these structures. Catheter-based ablation, using radiofrequency ablation or cryoablation, is a treatment option for various types of AF. Pulsed field ablation is a novel ablation technique for atrial fibrillation.
