Clinical Trial Summary

This study will compare efficacy and safety of pulmonary vein isolation using a cryoballoon catheter versus a radiofrequency ablation with a contact force sensing catheter for treatment of patients with persistent or longstanding persistent atrial fibrillation.


Clinical Trial Description

The purpose of this randomized clinical trial is to compare the efficacy and safety of pulmonary vein isolation with either the second generation cryoballoon (Arctic Front Advance™) or a radiofrequency ablation technique with an irrigated ablation catheter (TactiCath™ Quartz) . A total of 128 patients with persistent or longstanding persistent atrial fibrillation will be randomized for either radiofrequency or cryoballoon ablation treatment. With both techniques, pulmonary vein isolation will be performed and confirmed by a circular mapping catheter. The primary endpoint is freedom of any atrial arrhythmia recurrence at 12 months.Treatment success will be evaluated by using 12-lead electrocardiography and 7-day Holter recording. ;
