Does cryoballoon catheter ablation improve freedom from AT compared to radiofrequency catheter ablation in patients with AF undergoing PVI?
Cryoballoon and radiofrequency ablation provide similar efficacy for pulmonary vein isolation in atrial fibrillation, but present distinct safety profiles.
There was comparable freedom from AT between CB and RF in patients with AF undergoing PVI. Additionally, freedom from AT was similar between CB2 and CF-RF. However, CB was associated with a lower incidence of pericardial effusions or tamponade, albeit with a higher rate of transient phrenic nerve palsies.
Cardoso et al. (Sat,) studied this question.
