Efficacy and Safety Study on Agilis NxT Introducer in AF Patients

Ablation Success With the Use of Steerable AGILIS NxT Introducer Compared With Conventionally Used Swartz SL0.

To prove if the success rate of curative treatment of atrial fibrillation in left atrial circumferential pulmonary vein ablation is higher by using a steerable transseptal introducer giving access to the left atrium then by using a conventionally introducer with fixed curve.

To prove if the success rate of curative treatment of atrial fibrillation in left atrial circumferential pulmonary vein ablation is higher by using a steerable transseptal introducer giving access to the left atrium then by using a conventionally introducer with fixed curve; in patients with paroxysmal or persistent symptomatic Atrial Fibrillation.
