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.
Device: Catheter-based cardiac cryoablation
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||Clinical Study to Evaluate the Safety and Efficacy of the CryoCor™ Cardiac Cryoablation System for the Treatment of Cavo-Tricuspid Valve Isthmus-Dependent Atrial Flutter

| Study Start Date:
| Study Completion Date:
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.
|Ages Eligible for Study:
||18 Years to 75 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Symptomatic atrial flutter
- Prior ablation
- Contraindication to intervention
- Poor general health
