Study Completion Date: June 2005
Detailed Description:

Catheter ablation of arrhythmias has become an accepted alternative to pharmacologic therapy. Cryoablation is a newer alternative to radiofrequency ablations. This study expands the prior pilot experience with the CryoCor™ Cardiac Cryoablation System to a larger cohort of patients with atrial flutter.
