Support of diagnosis and therapy with 3D visualizations
Atrial fibrillation (AF) is one of the most frequently encountered arrhythmias in clinical settings. Electrical isolation of the pulmonary veins with radiofrequency ablation has become a well-established technique for treating AF. However, even if the success rates in preventing recurrence of AF episodes are high, this treatment is associated with a significant incidence of pulmonary vein (PV) stenosis, esophagus fistula and other rare complications.
To minimize these risks, 3D visualizations and analysis of the left atrium are necessary and important. Therefore, we developed syngo Inspace EP, a software application based on preprocedural CT or MR images to explore the following:
- See the left atrium and adjacent structures in 3D
- Explore the left atrium via an endoscopic view
- Overlay 3D visualization and live fluoroscopy
Our reference site Cleveland Clinic has performed over 300 procedures using syngo InSpace EP:

Step 1: CT or MR imaging
- Perform a Cardiac CT or MR scan
- Import DICOM data set into syngo InSpace EP application

Step 2: Fast and Reliable Segmentation of Left Atrium
- Fully automatic “one-click” segmentation of left atrium
- Rotate 3D image for best working projection
- Combine with visualization of the esophagus
- Planning under sterile conditions through integrated in-room display and remote control
Step 3: Endoscopic View for Procedure Planning
- Endoscopic view with “Fly Functionality”
- Measure, e.g., diameter and distances in the pulmonary vein ostia
- AutoMap adjusts C-arm of Artis zee to the projection of the displayed 3D image and vice versa
Step 4: Registration of CT and 3D Angio image
- Advanced algorithms for anatomical landmark registration
- 3D Fusion
Step 5: Overlay of LA segmentation with live fluoroscopy
- Visualize overlay on your live monitor in the lab
- Fade between display of fluoro and 3D
- segmentation Guide positioning of ablation catheters with the 3D LA
Step 6: Integration with CARTOMERGE™ module and recording system
- 3D segmentation result can be transferred to CARTO® system
- 3D image can be integrated in report of recording system
