Short Term Warfarin Therapy for Radiofrequency Catheter Ablation of Atrial Fibrillation
- Registration Number
- NCT01991951
- Lead Sponsor
- Korea University Anam Hospital
- Brief Summary
We hypothesized that in patients with low CHADS-VASc score (2 or \< 2), there is no difference in thromboembolic or bleeding events between patients with short term warfarin therapy (2 weeks after catheter ablation) and conventional therapy (3 weeks before and 8 weeks after procedure).
