Cardiovascular

EP Planning

• New Separately-licensed EP Planning option for VitreaCardiac EP Planning is a post processing advanced visualization application that is intended to be used for the analysis and assessment of the heart including the atria, pulmonary veins, and coronary sinus. The application provides analysis tools which include a number of display, quantitative measurement and 3D model export capabilities for use with the St. Jude Ensite® System. The application can be used to aid trained physicians in the visualization and assessment of cardiac anatomy.


EP Planning (continued)

• New Cardiac: EP Planning CT Protocol in the Gallery window

• Automatically segments left atrium

• Automatically probes pulmonary veins

• Easy Measurements and Analysis


EP Planning (continued)

• Show Esophagus - Window level in the esophagus and view in Heart mode

• View in Fly Through mode

• Save the 3D model, burn it to a blank CD, and send it to the EP lab


Vessel Probe

• New vessel tracking algorithm for carotid, renal, and peripheral vessels

• New visualization modes and layouts

- Larger images for detailed diagnosis

- Comparative cross-sectional display modes


Vessel Probe (continued)

Montage Layout

This is the default layout in the 1-up format. This view contains several 1mm cross-sectional views of the vessel.



Large Cross-sectional Layout

By default, the center cross-sectional inset displays the plane of the intersection with the middle of the curved view. This view contains three larger cross-sectional views.



CathView display mode (Angiographic overview image)

Cath view and 3D view project in the same plane.



• Image manipulation tools

- Automatic centering of 3D images

- Independent zooming for curved views



- Rendering menu and Thickness slider

Slider bar - thickness

Dropdown - rendering



- Rotating Curved MPRs

Left click/drag with crosshair on to rotate



- Auto-oblique Lock-Unlock

Scroll CPR views independent of oblique MPRs

Option to lock together (auto-oblique)

Button: Description:

Locked mode - Scrolling the insets will cause the global crosshair and oblique/curved planes to update. Unlocked mode - Unlocking resets the oblique planes to an orthogonal orientation. The lock will reset when a new patient is loaded.


Vessel Probe (Continued)

• Edit Function

• Quickly toggle in and out of “centerline edit mode”

• Click Edit to edit centerline in a 4-up viewer layout

• Click Edit again to return to the original viewing mode

• Show and Hide Centerline

Right-click on a vessel and click:

- Show Centerline or

- Hide Centerline



• Improved 2D editing

• 3D editingClick and drag to edit



• Analysis ToolsLesion tool: Three stenosis analysis modes

- Single Reference

Green cross section = reference 10 mm above (adjustable)

Red cross section = minimum diameter

- Average Reference

Averages diameter/area (top and bottom blue line) as the reference measurement


- Dual Reference

Allows average reference measurements and separate length measurements

Top and bottom green cross sections = reference


Blue line = length measurement



• Lesion Measurements

The percentage area stenosis is calculated using the new formula:

% area stenosis = (1 - Stenosed lumen area / Reference lumen area) × 100%

The percentage diameter stenosis is calculated using the new formula:

% diameter stenosis = (1 - Stenosed min lumen diameter / Reference min lumen diameter) × 100%
