Cryothermal ablation treatment of atrial flutter-experience with a new 9 French 8 mm tip catheter

Abstract. Background: Cardiac cryoablation has been used to successfully treat a variety of arrhythmias. Objective: This study documents our experience with a new 9 French (FR) 8 mm cryocatheter for ablation treatment of symptomatic atrial flutter. Methods: A total of 77 consecutive patients with symptomatic atrial flutter were treated. Electrophysi-ological studies (EPS) were performed with diagnostic catheters and ablation was performed with a 9FR, 8 mm tip, quadripolar cryocatheter (Freezor©R MAX catheter
