The RoadMap™ Analysis

The First Step to Coronary Artery Disease Diagnosis

The RoadMap analysis assists CT readers to accurately1, efficiently, and consistently identify stenoses in the coronary arteries. This anatomic visualization helps readers evaluate coronary CT angiograms before determining the need for an FFRCT. The RoadMap analysis easily integrates with HeartFlow’s Direct workflow.

The RoadMap Analysis Overview

Integrate the RoadMap Analysis With Ease

Anatomy + physiology available for all CCTAs.
Provides a preview of the severity and location of modeled stenoses > 30%.
FFRCT identifies physiologically significant lesions.

Bring Clarity to Every CCTA
With the RoadMap Analysis…

  • Color-coded capsules closely align with CAD-RADS 2.0 and indicate the location and severity of stenosis ≥ 30% for all vessels > 1.8mm.
  • Curved planar reformation (CPR) images provided for the LAD, LCX, and RCA with overlaid capsules.
  • Presence of plaque depicted on outer wall of anatomy overview image.
  • Integration into PACS for workflow convenience.

…And Help Guide Treatment Decisions With FFRCT

  • The AHA/ACC guidelines support the use of FFRCT in patients with 40-90% stenosis.
  • Management plans for over 66% of patients changed after physician received the FFRCT analysis compared to CCTA alone.2

Elevate Your CCTA Program With Consistency

The RoadMap analysis is proven to reduce inter-reader variability.3 With increased consistency of reads across CT readers, the RoadMap analysis can help CT readers ensure patients receive appropriate subsequent care and confidently determine the need for FFRCT.

Study Design

  • 50 coronary CTAs read were 3 times by certified Level 3 readers and processed 3 times by HeartFlow analysts.
  • Inter-reader agreement for CAD-RADS stenosis categories was assessed.
