Benefits of 3D QCA vs. 2D QCA

  • Elimination of foreshortening-overlap
  • Elimination of out-of-plane magnification
  • Highly accurate length, cross-sectional area and bifurcation angle measurements
  • Identification of optimal viewing angle

CONCLUSION

  • 3D bifurcation reconstruction feasible and time-efficient for ≥2 2D images
  • CAAS 3D 5.11 features full automatic calibration, reliability analysis and indicates the optimal viewing projection
  • It features novel, accurate and precise 3-D quantitative analysis of bifurcation lesions for diameter (multiple segment models), length and bifurcation angle measures.
  • Adding the optimal projection to a basic reconstruction of two suboptimal 2-D images results in higher accuracy and precision for MLD and DS values.
  • There is still work to be done regarding the in vivo validation of this software, in order to determine the clinical relevance of these data.
