Atrial Flutter

Title: Randomized Controlled Study of Remote Magnetic Catheter Navigation for Cavotricuspid Isthmus Mapping and Ablation in Patients With Typical Atrial Flutter
Number of Patients: 150
Trial Start Date: August 2007
Trial End Date: August 2009
Status: Recruiting
Purpose: The purpose of this randomized study is to evaluate the influence of remote magnetic catheter navigation on the safety and efficacy of mapping and radiofrequency ablation of the cavotricuspid isthmus in patients with typical atrial flutter.

Title: Multicenter Prospective Randomized Clinical Study Comparing Radiofrequency- vs. Cryo-Ablation in Typical Isthmus-Dependent Atrial Flutter
Number of Patients: 500
Trial Start Date: May 2003
Trial End Date: July 2008
Purpose: This study compares two energy sources (radiofrequency and cryo-ablation) for the catheter-based ablation of typical isthmus-dependent atrial flutter, regarding the acute and long-term efficacy and safety.
