Radiofrequency ablation has long been a standard of care, while cryoballoon technology has emerged as a feasible approach with promising results. Prospective multicenter registry data referring to both ablation technologies in AF ablation therapy are lacking.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Between January 2007 and August 2011, a total of 3,775 consecutive patients with symptomatic paroxysmal AF who underwent PV ablation in their respective centers were enrolled. 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). Comorbidities and baseline clinical characteristics were similar in both groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Acute success rate was similar in both groups (97.5% in cryo vs 97.6% in RF; P = 0.81). Procedure times were similar, ablation and fluoroscopy times were higher in cryoballoon when compared to RF ablation. Overall complication rate was similar in cryo\u2010 (4.6%) and RF\u2010ablation (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 &lt; 0.001). Other complications were more common in RF compared to cryoablation (4.6% in RF vs 2.7% in cryo; P &lt; 0.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>RF ablation is the most widespread ablation method in Germany, but use of cryoballoon increased significantly.
