Cryoballoon Ablation of Pulmonary Veins for Paroxysmal Atrial Fibrillation - STOP AF

Description:

Although radiofrequency ablation (RFA) after pulmonary vein isolation (PVI) for atrial fibrillation (AF) has been shown to be associated with a reduction in symptomatic AF, especially paroxsymal AF, it often requires multiple lesions, and may be associated with complications. Further, antiarrhythmic drugs (AAD) can also be associated with significant morbidity and mortality. Accordingly, the investigators sought to assess the safety and effectiveness of a novel cryoballoon ablation technology de...
