Does pulmonary vein ablation cure paroxysmal atrial fibrillation?
Does pulmonary vein ablation cure paroxysmal atrial fibrillation?
Pulmonary vein isolation is an effective strategy that can cure approximately 70% of patients with paroxysmal atrial fibrillation.
May support pulmonary vein isolation in paroxysmal AF; leaves open optimal selection and long-term durability via prospective trials.
Several investigators have identified the pulmonary vein as the most common initiator of atrial fibrillation, and isolation of the pulmonary vein from atrial tissue can cure approximately 70% of patients with paroxysmal atrial fibrillation. Ongoing trials of a new device may increase the success rate and decrease the complication rate during the pulmonary vein isolation procedure.
