Comparison between Contact Force Monitoring and Unipolar Signal Modification as a Guide for Catheter Ablation of Atrial Fibrillation: A Prospective Multi-centre Randomized Controlled Study (COMPASS study)
- Conditions
- Paroxysmal atrial fibrillation
- Registration Number
- JPRN-UMIN000021127
- Lead Sponsor
- Department of Cardiology, Tokyo Women's Medical University
- Brief Summary
nipolar signal modification was superior to contact force monitoring as an endpoint for radiofrequency energy deliveries during pulmonary vein isolation in patients with paroxysmal atrial fibrillation in terms of the 12-month recurrence free rate (85% vs. 70%, p=0.031).
