The CathWorks ffrangio system

Quantify. Decide. Confirm*.

Wire-free and drug free 3D FFR guidance, practical
for every case.

  • Generate an interactive 3D model of
    coronary tree, color-coded by FFR
  • Assess multi-vessel FFR and virtual FFR
    pullback curves in real time, before and after PCI*
  • Understand the comprehensive impact of CAD
    across the full coronary tree with FFRangio | IMPACT**
  • View 3D QCA and diameter measurements across entire vessel lengths

Powerful Technology. Impactful Information.

The CathWorks FFRangio System combines routine angiograms and advanced
computational science to give you a powerful
and practical CAD decision tool.

  • 1
    During the procedure, 2D angiograms are converted into an accurate digital 3D model of the coronary tree.
  • 2
    Super-computer analyzes each vessel in 3D, evaluating vessel shapes and blockages along each vessel.
  • 3
    Using proven scientific principles, algorithms solve millions of equations to calculate FFR at every point in the tree.
