Condition atrial fibrillation
Treatments catheter ablation for atrial fibrillation, manual, ablation using amigo remote catheter system
Sponsor University of Leicester
Start date April 2012
End date December 2017
Trial size 50 participants
Trial identifier NCT01583855, UNOLE 0260


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).

Additional Information

Official title Manual vs Amigo SmartTouch Atrial Fibrillation Study
Principal investigator G Andre Ng, MBChB, PhD
Description The trial aims to recruit 50 patients, randomised into two groups, to have ablation for atrial fibrillation performed either using the RCS, or manually. Contact force information will be collected during the procedure, but the operators will be blinded to this information. Patients will have follow-up to include post-procedural cardiac magnetic resonance imaging and ambulatory electrocardiograms.
