Abstract 15358: Improving Visualization and Interaction During Transcatheter Ablation Using an Augmented Reality System: First-in-Human Experience
Introduction: A novel augmented reality (AR) based system that displays a real time intraprocedural hologram of cardiac geometry, electroanatomic maps, catheter localization with a controllable via sterile interface was developed. The system improves physician visualization and data interaction, which we expect will improve understanding of patient-specific cardiac anatomy and ultimately improve physician performance resulting in improved patient outcomes. We present the first live case where we have used this system, the Enhanced ELectrophysiology Visualization and Interaction system (ēLVIS).
Methods: Software developed with the Windows Mixed Reality platform was loaded onto the Microsoft HoloLens (HL) augmented reality head mounted display and tested with historic data, prior to use in a live study.
Results: During a standard electrophysiology study and transcatheter ablation, ēLVIS displayed a holographic projection of real time cardiac geometry during its creation and throughout the case. Local activation time (LAT) map, catheter locations and lesion markers were all overlaid onto this model. Two concurrent observers located outside the electrophysiology suite watched the live case and interacted with the model altering the scale, rotation and translating the geometry using gaze/gesture control. Baseline metrics included battery usage of 27%/hour (3.7 hours of runtime), CPU load of 55±12.5%, and a framerate of 21±3.4 fps while displaying 6000±5600 triangles. Figure shows holographic image collected during case.
Conclusion: Display of real time cardiac geometry, LAT map, catheter localization and lesion data in a single hologram within an AR environment that facilitates physician visualization, interaction and collaboration is feasible. Future studies will include usability testing and prospective in-human validation.
