Study Objective - The objective of the prospective, randomized study is to evaluate the effectiveness and safety of the Baylis transseptal system (RF needle, TorFlex sheath, and specialised ProTrack guidewire) compared with a conventional transseptal (conventional sheath, Brockenbrough needle, and standard guidewire) for transseptal LA access during cryoballoon ablation procedures.~Trial design - This will be a prospective single-blinded, randomized, controlled trial comparing the effectiveness and safety of transseptal puncture using the Baylis transseptal system to transseptal left atrial access with standard transseptal equipment (usual care) in patients undergoing catheter ablation procedures for atrial fibrillation with the cryoballoon system.~Study Population - The targeted population will consist of patients with symptomatic paroxysmal atrial fibrillation undergoing pulmonary vein isolation with the cryoballoon system.
