The CathWorks ffrangio® system

Quantify. Decide. Confirm.*

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

  • Interactive 3D reconstruction of coronary tree,
    color-coded by FFR value
  • Highly accurate FFR results for multiple vessels
  • Angiograms overlaid with QCA and FFR for
    anatomical context
  • Interactive vessel sizing tool and 3D QCA for procedural planning

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, an AI-based platform transforms 2D angiograms into an accurate digital 3D model of the coronary tree.
  • 2
    Advanced algorithms evaluate blockages, 3D QCA, and flow resistance along each vessel.
  • 3
    Using proven scientific principles, a rapid pressure-flow analysis calculates FFR values at every point in the tree, revealing segments that may need intervention.

Three Advanced Clinical Decision Tools.
One Powerful System.

Comprehensive physiologic and anatomic insights guide a
personalized treatment plan for every patient.

  1. The FFRangio I IMPACT** adds important context around the burden of CAD across the full tree.
  2. The FFRangio I PULLBACK shows where FFR drops occur, helping you differentiate diffuse from focal disease and target the most important areas.


Interactive Vessel
Sizing Tool

New vessel sizing tool based on accurate 3D QCA allows you to quickly estimate lesion lengths and vessel diameters for procedural planning. The sizing tool is displayed on the 3D QCA chart and angiograms for anatomical context.
