Brief Summary:
The purpose of this study is to evaluate the safety and efficacy of right atrial intra-cardiac lesions created by transvenous catheter cryoablation in patients with atrial flutter.

Condition or disease Intervention/treatment Phase
Atrial Flutter Device: Catheter-based cardiac cryoablation Phase 3

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.
