The aim of this study is to evaluate the safety and feasibility of using the Amigo
Remote Catheter System (RCS) in arrhythmia ablation procedures. Because Amigo allows
the physician to operate all catheter function outside of the radiation field, operator
exposure time was also evaluated. This is a nonrandomized, prospective clinical trial
conducted at 1 site (identifier: NCT01834872). The study prospectively enrolled 50 consecutive patients (mean age 59 ± 15 years,
72% men) with any type of arrhythmia (23 atrial fibrillation ablation, 12 common atrial
flutters, 10 patients with other supraventricular tachycardia, 4 ventricular tachycardia,
and 1 patient with palpitations with no arrhythmia induced) referred for catheter
ablation, in which we used RCS. Fifty matched ablation procedures (mean age 57 ± 14 years,
70% men) performed during the same time period, without RCS, were enrolled into the
control group. Acute ablation success was 96% with RCS and 98% in the manual group.
In only 2 cases, the physician switched to manual ablation (1 ventricular tachycardia
and 1 accessory pathway) to complete the procedure. There were no complications related
to the use of RCS. No differences were observed in total procedure time, total fluoroscopy
time, or total radiofrequency delivery compared with the manual group. In procedures
performed with RCS, the operator's fluoroscopy exposure time was reduced by 68 ± 16%.
In conclusion, arrhythmia ablation with RCS is safe and feasible. Furthermore, it
significantly reduces operator's exposure to radiation.
