Cryoablation for persistent and longstanding persistent atrial fibrillation: results from a multicentre European registry
Why the study?
Although cryoballoon pulmonary vein isolation is established for paroxysmal AF, its role in persistent and longstanding persistent AF remains unclear.
Does cryoablation prevent arrhythmia recurrence in patients with persistent and longstanding persistent atrial fibrillation?
Comparison
Cryoablation in persistent vs longstanding persistent AF
Design
International multicentre prospective registry
Follow-up
Median 2.4 (1.0-4.0) years

Implication
Supports the feasibility of cryoballoon ablation for persistent AF in real-world practice;.
Structured PICO
Does cryoablation prevent arrhythmia recurrence in patients with persistent and longstanding persistent atrial fibrillation?
P
Population
609 consecutive patients with persistent and longstanding persistent atrial fibrillation
I
Intervention
Cryoablation (cryoballoon pulmonary vein isolation)
O
Outcome
Freedom from AF or atrial tachycardia lasting >30 s off antiarrhythmic drugs (AADs)
Cryoablation demonstrates good long-term efficacy for persistent and longstanding persistent AF, achieving a 61% single-procedure success rate off antiarrhythmic drugs over a median of 2.4 years.
