Why the study?
Does cryoballoon ablation using the novel Achieve inner lumen mapping catheter achieve pulmonary vein isolation safely in patients with drug-resistant paroxysmal atrial fibrillation?
Does cryoballoon ablation using the novel Achieve inner lumen mapping catheter achieve pulmonary vein isolation safely in patients with drug-resistant paroxysmal atrial fibrillation?
Cryoballoon ablation using the novel Achieve catheter is feasible and safe, achieving pulmonary vein isolation in 98% of veins without needing a regular guidewire, though real-time recordings were only possible in 47% of veins.
