Does the single big cryoballoon technique achieve acute pulmonary vein isolation in patients with paroxysmal atrial fibrillation?
The single big cryoballoon technique is highly effective for acute pulmonary vein isolation (98% success) without requiring left atrial imaging.
Using the single big cryoballoon technique, almost all PVs (98%) could be electrically isolated without LA imaging and may reduce the incidence of PNP as long as distal ablation inside the septal PVs is avoided.
