Key result
In patients with atrial fibrillation undergoing cryoballoon ablation, those ≥75 years had similar arrhythmia recurrence rates compared to those <75 years (30% vs 25%, P=0.62).
Why the study?
Does pulmonary vein isolation using second-generation 28mm cryoballoon ablation improve arrhythmia recurrence in patients ≥75 years with atrial fibrillation?
Cohort (n=80)
Does pulmonary vein isolation using second-generation 28mm cryoballoon ablation improve arrhythmia recurrence in patients ≥75 years with atrial fibrillation?
Absolute Event Rate: 30% vs 25%
p-value: p=0.62
Second-generation cryoballoon ablation for atrial fibrillation demonstrates similar efficacy and safety in patients ≥75 years compared to younger patients.

Supports cryoballoon ablation in AF patients ≥75 years; leaves open randomized confirmation of age-independent efficacy.
Tscholl et al. (2017) conducted a cohort in Atrial fibrillation (n=80). Age ≥75 years vs. Age <75 years was evaluated on Arrhythmia recurrence (p=0.62). In patients with atrial fibrillation undergoing cryoballoon ablation, those ≥75 years had similar arrhythmia recurrence rates compared to those <75 years (30% vs 25%, P=0.62).
