简要总结
It's a multi-center, prospective, randomized, controlled clinical trial of cryoballoon versus radiofrequency ablation for paroxysmal atrial fibrillation.
详细描述
The hypothesis of this study is that pulmonary vein isolation with cryoballoon ablation is not inferior to radiofrequency ablation with 3D mapping with respect to clinical safety and efficacy.
