Summary

Three-dimensional (3D) mapping systems have been introduced to facilitate catheter navigation during interventional treatment of complex arrhythmias. However, current technologies do not sufficiently compensate for respiratory, cardiac cycle and patient movement. A novel sensor-based electromagnetic 3D navigation system (MediGuide Technology, St. Jude Medical, Inc., St. Paul, MN, USA) has recently been introduced to offset these limitations. A transmitter-generated 3D electromagnetic field is the main component of the MediGuide technology. In this field, a miniaturized single coil sensor assembled within an intracardiac device such as a conventional electrophysiology catheter can be visualized and tracked non-fluoroscopically in prerecorded ciné loops. Unlike other 3D mapping systems, this technology provides online compensation for movement. After a feasibility study to validate the MediGuide System with respect to non-fluoroscopic catheter placement, respiratory, patient movement and cardiac cycle compensation, and accuracy of catheter visualization, the system has been used to facilitate catheter navigation during different electrophysiology procedures such as cavo-tricuspid isthmus, atrial fibrillation ablation and the treatment of ventricular arrhythmias.
