    The Amigo Remote Catheter

    System is a new robotic system

    for catheter navigation recently

    used for electrophysiological

    procedures with promising

    results. However no data are

    available about the contact

    force produced to the cardiac

    tissue by the use of this remote

    navigation system versus

    traditional manual catheter

    manipulation.

    To evaluate contact force (CF) during atrial fibrillation (AF) ablation using AMIGO robotic system (ARs) as compared to manual combined to Thermocool SmartTouch catheter (STc).

    The system consists of a robotic arm installed on the patients table

    and a remote controller connected to the robot through a cable.

    The ablation catheter is introduced into the patients right femoral

    vein through a conventional sheath (7-8 F) and advanced manually

    into the cardiac chamber of interest; then, the catheter steering

    handle mechanism is attached to Amigo and the operator controls

    catheter navigation with the remote controller from the control

    room, away from the fluoroscopy field. The remote manipulator

    controller imitates the operation of the catheter by the

    conventional handle: forward and backward, deflection, and torque

    (rotation). At any point during the procedure, the catheter can be

    removed from the robotic arm for manual manipulation and can

    also be re-attached to the robot without breaking sterility.

    Twenty-eight consecutive

    patients (pts) (mean age

    55.26.8 year, 18 males),

    referred to our centre for

    paroxysmal AF, were

    randomized to receive

    pulmonary veins (PV) isolation

    by either a standard manual

    procedure (MP) with STc or a

    robotic procedure (RP)

    combining STc to ARs. Contact

    force data were measured and

    stored by CARTO3 system.

    Pulmonary vein (PV) isolation was reached in all cases. No clinical

    complications occurred. Mean fluoroscopy time: 6.52 min for RP;

    14.59 min for MP (p0,001). Mean procedural time: 14219 min

    for RP; 17036 min for MP (p=0,01). Mean CF data among the PVs:

    a) LSPV: 14.37.4 g for RP; 12.87.8 g for MP (p
