Evaluating catheter usage for atrial fibrillation ablation: improving rates of efficacy and safety

Radiofrequency remains a milestone, especially in the field of the point-by-point ablation manner. The introduction of the temperature-controlled ablation catheters allows ablation with higher power settings compared to standard power-controlled ablation, resulting in high acute and one-year success rate with a low incidence of complications. Similar results have been reported with both cryoballoon ablation system, with shorter procedural time and longer fluoroscopy time. Pulsed field ablation is a novel ablation modality, largely nonthermal, aiming at creating transmural, durable ablation lesions while reducing the risk of collateral damage.
