Supports no-bonus freeze cryoballoon PVI; leaves open randomized confirmation versus standard protocols.
Does a 'no-bonus' freeze protocol using the second-generation 28 mm cryoballoon prevent arrhythmia recurrence in patients with drug-refractory atrial fibrillation?
A 'no-bonus' freeze protocol for PVI using the second-generation 28 mm cryoballoon achieves an 82% 1-year clinical success rate, suggesting that a bonus freeze cycle may not be essential for superior clinical outcomes.
Wißner et al. (2015) studied Drug-refractory paroxysmal or persistent atrial fibrillation (n=45). 'no-bonus' freeze protocol using the second-generation 28 mm cryoballoon was evaluated on Stable sinus rhythm. A 'no-bonus'-freeze protocol for pulmonary vein isolation using the second-generation 28 mm cryoballoon resulted in an 82% 1-year clinical success rate.
