Overview
With CAAS QCA 2D Bifurcation, we have developed a dedicated QCA program to assess bifurcation lesions. CAAS QCA 2D Bifurcation is an option on the standard CAAS QCA software.
Analysis of bifurcated arteries
Coronary artery bifurcation lesions pose a major challenge for interventional cardiologists as percutaneous treatment of these lesions is associated with increased risks of complications. Evaluation of dedicated stenting devices, using the conventional QCA without dedicated bifurcation option, has limitations. This is due to vessel diameter changes over the bifurcation. Another complication lies in defining the true reference vessel size (healthy vessel) within the bifurcation area. You can overcome these limitations and achieve the most accurate bifurcation analysis by using CAAS QCA 2D Bifurcation
Key Product Features:
- Treats the bifurcation as a single unambiguous object
- Vessel border detection for bifurcations
- Easy contour edits
- Automatic and user defined reconstruction of the healthy vessel shape for the total bifurcation as one unambiguous object
- Automatic calculation of bifurcation angles
- Quantification of lesion length and percentage stenosis
Import / Export
CAAS accepts DICOM files with single and multi-frame, monoplane and biplane images.
The results can be exported as:
- DICOM secondary capture. The image with overlay and analysis report can be saved as DICOM SC. This results in a “what you see is what you get” report.
- DICOM structured report. The calculated results can be saved as DICOM SR. This can be used to generate reports based on the analysis results
- XML. The calculated results can be saved to XML. Pie Medical Imaging provides a dedicated toolkit for transformation of XML files to TXT files.
Key Benefits:
- Digitally saved reports
- Several report formats
- Customizable templates
Workflow
