Why the study?

Does omitting a bonus-freeze improve procedure times without increasing atrial fibrillation recurrence in patients undergoing cryoballoon pulmonary vein isolation?

Population

120 consecutive patients with paroxysmal or persistent atrial fibrillation undergoing second-generation…

Bonus-freeze applied after successful pulmonary… vs No bonus-freeze protocol.

Implication

Omitting bonus-freeze shortened procedures without higher recurrence in this cohort; leaves open randomized confirmation before practice change.

Does omitting a bonus-freeze improve procedure times without increasing atrial fibrillation recurrence in patients undergoing cryoballoon pulmonary vein isolation?

Population

120 consecutive patients with paroxysmal (79%) or persistent (21%) atrial fibrillation undergoing second-generation cryoballoon based pulmonary vein isolation.

Intervention

Bonus-freeze applied after successful pulmonary vein isolation (freeze-cycle duration 240 s).

Comparator

No bonus-freeze protocol (bonus-freeze omitted after successful pulmonary vein isolation).

Outcome

Long-term clinical outcome (stable sinus rhythm) and safety profile (procedural complications, procedure and fluoroscopy times) at mean follow-up of >2 years.
