Ablation of atrial fibrillation using the fourth-generation cryoballoon Arctic Front Advance PRO.

The cryoballoon (CB) is a popular ablation technology used for pulmonary vein isolation. The fourth-generation CB, Arctic Front Advance PRO features a 40% shorter distal tip but retains the internal design from its second-generation predecessor. The Arctic Front Advance PRO and the second-generation CB demonstrated similar thermodynamic characteristics in a computational model. Several observational and retrospective studies established the acute safety and efficacy of the Arctic Front Advance PRO. Real-time electrical isolation was observed in 75-85% of pulmonary veins targeted with the Arctic Front Advance PRO resulting in shorter fluoroscopy and procedure times.
