Why the study?
Does radiofrequency catheter ablation of pulmonary vein foci prevent atrial fibrillation recurrence in patients with paroxysmal atrial fibrillation?
Does radiofrequency catheter ablation of pulmonary vein foci prevent atrial fibrillation recurrence in patients with paroxysmal atrial fibrillation?
Radiofrequency catheter ablation of pulmonary vein foci is an effective treatment for achieving freedom from paroxysmal atrial fibrillation, with a low rate of clinically significant pulmonary vein stenosis.
No takes yet. Share an insight, caveat, or question.
May support pulmonary vein ablation in paroxysmal AF; leaves open long-term durability and need for randomized trials.
