Key result
Second-generation cryoballoon ablation performed by junior operators resulted in similar midterm outcomes compared to a senior operator (79.5% vs 83.3%, P=0.589).
Why the study?
Does second-generation cryoballoon ablation performed by inexperienced operators achieve similar safety and efficacy as senior operators in patients with atrial fibrillation?

Absolute Event Rate: 79.5% vs 83.3%
p-value: p=0.589
Velagić et al. (2016) conducted an observational in Atrial fibrillation (n=300). Ablation by junior operators vs. Ablation by senior operator was evaluated on Midterm outcomes (p=0.589). Second-generation cryoballoon ablation performed by junior operators resulted in similar midterm outcomes compared to a senior operator (79.5% vs 83.3%, P=0.589).
