Experience Using of EnSite Precision^TM Software Version2/Auto Map Module

Perspective from E-journals in J-STAGE

Abstract

The EnSite system has been widely applied to catheter ablation procedures in Japan. Using EnSite Precision^TM Software Version2 /Auto Map Module（Ver2）offline analyzer, we retrospectively created 3D images during tachycardia using auto map, fractionation map and score map for individual cases and identified the features of these functions added by Ver2. The auto map, depending on its settings, could be made into a high-density map compared with the manually prepared activation map. However, it was difficult to identify the tachycardia circuit at both the atrial and ventricular electrogram recording sites. The fractionation map was useful to determine the optimal ablation site by transferring the fractionated potentials to activation map. The score map, showing the location information of pace mapping score, was considered useful in ablation for premature ventricular contraction. But locational adjustment was required when creating the map. Even though the EnSite system has become more useful as a result of advanced mapping modules, it was necessary to grasp their features before applying this system.
