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 Intervention Phase
Atrial Flutter Device: Catheter-based cardiac cryoablation Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: 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

Further study details as provided by Boston Scientific Corporation:

Primary Outcome Measures:
  • Acute efficacy
  • Acute safety

Secondary Outcome Measures:
  • Long-term efficacy
  • Long-term safety

Estimated Enrollment: 160
Study Start Date: January 2004
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.
