Measure
Manual Catheter Manipulation
25 subjects will be randomized to this arm. Manual catheter ablation of the cavo-tricuspid isthmus will be performed. Manual Catheter Manipulation: Ablation is a standard procedure that patients may undergo for the atrial flutter. In this study, this group will be assigned to manual catheter manipulation.
Amigo™ Robotic Catheter Manipulation
25 subjects will be randomized to this arm. Robotic catheter ablation of the cavo-tricuspid isthmus with the Amigo Catheter System will be performed. Amigo™ Robotic Catheter Manipulation: Ablation is a standard procedure that patients may undergo for the atrial flutter. In this study, this group will be assigned to robotic catheter manipulation.
