Conventional fluoroscopy is the main technology for intracardiac device tracking in interventional cardiovascular procedures. For therapy delivery it carries the advantage of being able to instantaneously localize the device and its spatial relationship with respect to the moving target organ. However, besides the associated X-ray exposure, fluoroscopy only provides 2D orientation. For treatment of complex cardiac anatomies and substrates such as in interventional electrophysiology, 3-D mapping technologies have been introduced to facilitate spatial, anatomic, and electrical orientation. A new technological platform (MediGuide(™)) offers the option to continuously display the catheter tip on a prerecorded cine-loop allowing better anatomic understanding of the underlying substrate. We describe our initial experience using the system with diagnostic catheters only and the first procedures with the MediGuide(™) equipped ablation catheter (available since May 2012). We could show a significant decrease of fluoroscopy time in all types of procedures with comparable procedure times. No increase in complication rates was observed.
