The MediGuide Positioning System can be utilized for real-time navigation during atrial flutter ablation in patients with a HeartMate II left ventricular assist device.
May facilitate ablation navigation in LVAD patients; leaves open safety, efficacy, and need for prospective trials.
The increasing complexity and duration of electrophysiology procedures have led to the development of alternative methods of mapping and ablation. One recent technological advance is the MediGuide Positioning System (St. Jude Medical, St. Paul, MN). This system superimposes electromagnetic field tracking over prerecorded fluoroscopic cine loops, with dynamic compensation for respiratory and cardiac motion. This system facilitates real-time navigation while reducing the need for additional fluoroscopy.
