Accuracy of Catheter Guidance Technology in the EP Lab Background With increasing complexity electrophysiology (EP) procedures, use electroanatomic mapping systems (EAMS) as a supplement to fluoroscopy has become common practice. This is first study that evaluates spatial and point localization accuracy for 2 current EAMS, CARTO3 ® (Biosense Webster, Diamond Bar, CA, USA) EnSite Velocity (St. Jude Medical Inc., St. Paul, MN, USA), novel overlay guidance (OG) software (Siemens AG, Forchheim, Germany) phantom experiment. Methods Results A C‐arm CT scan was performed on an acrylic containing holes location markers. Spatial assessed each system using distance measurements involving known markers inside properly placed catheters. Anatomical maps were acquired by whereas 3D‐based OG superimposed image phantom, segmented from data set, onto biplane fluoroscopy. Registration processes landmark quantitatively technology with respect ground truth phantom. Point performance 0.49 ± 0.25 mm OG, 0.46 0.17 0.79 0.83 . The registration offset between virtual visualization reality 1.10 0.52 1.62 0.77 2.02 1.21 0.30 0.26 0.24 0.21 1.32 0.98 Conclusions Each evaluated showed high level accuracy; observed offsets 3D real below clinically relevant threshold 3 mm.
