Stereotactic Systems, Image-Guided, Cardiac Mapping/Ablation
Definition : Stereotactic image-guided computer-aided systems designed to provide the capability to map the three-dimensional (3-D) anatomy of the heart. They are also designed to determine the electrophysiologic data at any given mapped-out point, design the ablation strategy, and then return accurately to the desired site to aid in the performance the ablation procedure. These systems typically consist of a cardiac catheter with electrodes and miniaturized coils at the tip, a magnetic-field generator located underneath the patient, a computerized unit to process the currents induced in the coils when the catheter is moved, and a graphical display on which images are a real-time representation of the 3-D geometry of a cardiac chamber, color-coded with relevant electrophysiologic information. Cardiac mapping/ablation image-guided stereotactic systems are used to improve the safety of mapping and ablation procedures through accurate localization of critical cardiac structures (e.g., His bundle, atrioventricular node), allowing better definition of the mechanisms of arrhythmias, design of ablation strategies, and guided catheter ablation.
