NCT06183879

Brief Summary

The goal of this clinical trial is to compare two different, market approved, cryoballoon devices for the treatment of paroxysmal atrial fibrillation (AF). The main aims of the study are:

  • to compare the efficacy of two ablation devices (acute and 1 year success rates)
  • to compare the procedural characteristics (procedure duration, fluoroscopy duration, ablation time
  • to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon. Standard of care cryoballoon procedure will be performed alongside with standard postprocedural follow-up.
  • to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon.
