Morphology: Automatic calcium detection²

1 in 4 patients undergoing PCI, have moderate to severe calcium.³ If left undiagnosed and untreated, it adversely impacts PCI outcomes.⁴ Calcified lesions limit stent expansion, which is a major predictor of stent failure, such as stent thrombosis and restenosis.⁵

Ultreon Software displays calcification on the morphology screen:

• An orange arc around the cross-sectional view indicates the presence of calcium
• Arc is displayed when calcium angle is at or above 60 degrees of circumferential calcium — Learn more about how to identify calcium with OCT
• The white triangle, marked by the red circle, in the cross-sectional view indicates maximum calcium thickness [in the current frame]
• Total angle and max thickness values are displayed in real time throughout pullback
• Co-registration allows the user to visualize the calcium on the angio still frame

When calcification assessment is complete, a user can click on the Sizing tab to proceed to the next step of stent sizing evaluation.

Sizing: Automatic detection of vessel diameter via EEL or Lumen²

Ultreon™ 1.0 Software uses artificial intelligence (AI) to automatically detect external elastic lamina (EEL) and lumen to help identify landing zones for accurate stent placement.^1,6

• Length: Angiography co-registration facilitates identification of accurate length
• Diameter: External elastic lamina (EEL) and lumen help identify landing zones in healthy tissue for stent placement⁶
  • Lumen shown as a solid white or red contour line
  • EEL shown as the dotted white line in the cross-sectional image and lumen profile

Sizing screen displays a four panel view:²

1. Current selected frame
2. Proximal reference frame
3. Distal reference frame
4. Maximized lumen profile – user can maximize the lumen profile by clicking on the icon at top left corner of lumen profile view.

Once sizing assessment is complete, a user can move to the next step by clicking the Deployment tab.

Deployment: Facilitation of precise stent deployment²

Ultreon™ 1.0 Software facilitates accurate stent deployment through co-registered and live angio views side-by-side.

• Users can select a full-screen co-registered view if desired

Once the stent deployment is complete, a user can move to the next step by clicking the Review tab for post-PCI optimization.

Review: Post-stent optimization²

Ultreon™ 1.0 Software displays instantaneous calculations of expansion and apposition values, reference lumen diameter and lumen diameter values in color-coded markers:

• Stent underexpansion indicator — orange
• Stent malapposition indicator — yellow

Malapposition Indicator²

Ultreon™ 1.0 Software helps ICs to quickly detect stent malapposition on the cross-sectional and lumen profile views:

• On the cross-sectional view, malapposed struts are indicated by yellow dots if the gap between the strut and the vessel wall exceeds the user’s preselected threshold setting.
• On the Lumen profile, malapposed zones are indicated by yellow bands when there’s a cluster of malapposed struts of length ≥ 1 mm and maximum circumferential angle ≥ 90 degrees

Pullback Comparison²

Physicians can quickly compare any two pullbacks by clicking on the Menu icon in the upper right corner. See the result of your PCI through vessel visualization pre- and post-stenting on one screen.
