NCT01583855

Brief Summary

Atrial fibrillation is a common form of heart rhythm disturbance that for some patients is treated by catheter ablation (making an ablation lesion or burn inside the heart using a fine wire (catheter)). A new system for manipulating the catheters has recently been introduced into clinical practice (the Amigo Remote Catheter System (RCS)). This trial is designed to answer two primary questions: a) is the contact force (the force with which the catheter comes into contact with the heart) any different using the RCS to manual techniques,and b)are the resulting ablation lesions within the heart any different in terms of the volume and contiguity of the lesions produced. Additionally the investigators aim to determine how the two techniques compare in success (the proportion of patients whose heart rhythm disturbance is corrected by the procedure).
