A 3D rendering of the 2D CTA data is visualized. Select automatic for automatic segmentation and centerline detection of the aortic root.
2. Aortic Root Analysis
The annulus plane can be easily defined by marking the nadir of the leaflets. The centerline can be checked and adjusted in 4 viewports.
3. Aortic Root Analysis
In the measurements step, diameter and length measurements can be performed and stored in the report. A MinIP view is provided to assess the leaflets without calcification. In the Hockey Puck viewport, the calcification of the Aortic Valve can be assessed.
4. Aortic Root Analysis
An angio view is provided for optimal calculation of c-arm angulation prior to the actual intervention. Double oblique views show 2D and 3D information about the mitral and aortic valve.
1. Subclavian Approach
To assess the subclavian approach, perform an Automatic segmentation of the aorta and subclavian in one mouse click.
2. Subclavian Approach
Two control points are placed on the vessel for centerline detection. Centerline points can be added, deleted or dragged to the required position.
3. Subclavian Approach
A stretched view is provided, showing the calcifications of the vessel. Possible problem areas indicated throughout the entire trajectory for the catheter based on automated diameter is shown in the measurement panel.
1. Apex Approach
To assess the Transapical approach after the Aortic Root Analysis, indicate the Apex with a left mouse click.
2. Apex Approach
A double oblique MPR is shown containing a virtual catheter. The location and size of the catheter can be adjusted. Measurements of the septal wall and myocardium thickness can be performed and assigned to the report.
3. Apex Approach
A 3D view is provided with the virtual catheter to assess the intercostal space and entry point prior to the operation.
1. Femoral Approach
To asses if a transfemoral approach is feasible, start with segmenting the aorta and iliac arteries by a single left mouse click. Other vessels can be added to the segmentation.
2. Femoral Approach
Three control points are placed on the vessel in the aorta, right and left iliac artery for centerline detection.
3. Femoral Approach
The centerline is automatically calculated and can be checked in the viewport. Centerline points can be added, deleted or dragged to the required position.
4. Femoral Approach
Two stretched views and a measurement panel are provided showing the calcification and automated diameter measurements. The measurement panel also indicates tortuous areas of the vessel.
Prepare TAVR (or TAVI) interventions with 3mensio Structural Heart. The Aortic Root workflow provides a quick, easy and reliable way to plan and size for aortic valve replacement. The intuitive workflow assistant guides the user through the CT image analysis to obtain the needed measurements.
Dedicated workflows help the user to rapidly determine the appropriate access route for each patient; Transfemoral, Subclavian, Transapical or Direct Access.
