Including QFR® analysis
The accurate 3D QCA reconstruction offered by QAngio® XA 3D is the back bone for PCI treatment:
QAngio XA 3D provides all the anatomical parameters for stent sizing, the optimal viewing angles for visualizing the lesion area, and the physiologic assessment (QFR) of one or more lesions at the same time.
QAngio XA 3D is the analytical software solution for the reconstruction of a coronary artery from two X-ray angiographic projections at least 25 degrees apart, either from a biplane acquisition or from two monoplane acquisitions, and the subsequent QCA analysis of clinically relevant parameters of coronary obstructions.
3D QCA analysis
QFR (Quantitative Flow Ratio) analysis
QFR calculated from 3D QCA according to 3 different flow models:
- Fixed flow QFR, using fixed flow velocity
- Contrast QFR, using contrast frame count in an angiogram without hyperemia
- Hyperemic QFR, using contrast frame count in angiogram, taken in adenosine-induced hyperemic condition
