The cohort was divided into 2 groups according to the ablation energy source used: cryoballoon ablation (group 1, n = 905 [24.0%], median age 63 years, 64.3% men) and RF ablation (group 2, n = 2870 [76.0%], median age 63 years, 62.7% men).

Procedure times were similar, ablation and fluoroscopy times were higher in cryoballoon when compared to RF ablation. Overall complication rate was similar in cryo- (4.6%) and RF-ablation (4.6%; P = 1.0). Phrenic nerve palsy was more often in cryo versus RF ablation (2.1% in cryo vs 0.0% in RF; P < 0.001). Other complications were more common in RF compared to cryoablation (4.6% in RF vs 2.7% in cryo; P < 0.05).CONCLUSION: RF ablation is the most widespread ablation method in Germany, but use of cryoballoon increased significantly.
