Abstract:
High-definition (HD) mapping with the Advisor HD Grid and HD Wave Solution software offers unparalleled resolution in mapping complex arrhythmias. The unique shape of a HD Grid (16 electrodes in a 4 × 4 pattern) allows for the mapping of orthogonal electrograms (EGMs). In so doing, the HD Grid catheter virtually eliminates the issue of 'bipolar blindness', a phenomenon seen when a wavefront of propagation is traveling perpendicular to a bipole pair. By improving the accuracy of the 3D electroanatomical map, HD Grid offers the potential of shorter procedure times, safer ablations and higher success rates. The following article explores the role of HD Grid in mapping a variety of arrhythmias including supraventricular tachycardias, atrial fibrillation and ventricular tachycardia. In addition, the authors explore the role of HD Grid in more recently described substrate-based advanced mapping techniques.
