Use of a Mixed Reality System for Navigational Mapping During Cardiac Electrophysiology Testing Does Not Prolong Case Duration: A Sub-analysis from the Cardiac Augmented Reality Study

BackgroundCommandEP™ is a mixed reality (MXR) system for cardiac electrophysiology (EP) procedures providing real time 3-dimensional digital image of geometry and catheter locations. In previous study, physicians using the demonstrated improved navigational accuracy. This study investigated impact CommandEP on EP procedure times compared to standard-of-care electroanatomic mapping (EAMS) display.ObjectiveThis retrospective case-controlled analysis evaluated novel MXR interface case-matched cohort.MethodsCases from Cardiac Augmented REality (CARE) were matched diagnosis, weight contemporary cohort. Procedural was roll-in full implementation During routine procedures, operators performed tasks during post-ablation waiting phase, including creation 5-point navigation under 2 conditions: 1) EAMS first, 2) CommandEP.ResultsFrom total 16 CARE patients, 10 patients cohort 20 control (2 controls:1 CARE, according pathology age/weight)). No statistical difference in case between vs group (118±29 97±20min, p=0.07) or fluoroscopy (6±4 7±6 min, p=0.9). significant duration comparing versus full-implementation (121±26 118±29 p=0.96). wear cases significantly longer (53±24 24±5min, p=0.0009). single geometry, no noted (284±45 268±43 sec, p=0.1) use (9±19 6±18 p=0.25). point tasks, there (CommandEP 31±14 28±15 p=0.16) 0 sec sec).ConclusionMXR did not prolong overall There prolongation task completion time. Future studies with experienced users directly assessing randomized population would be interest.
