Advancing Cath Lab Results With FFRangio Coronary Physiology Assessment


To test whether FFRangio-guided treatment is non-inferior to conventional pressure wire-guided treatment in patients with coronary artery disease.


Adult patient ( ≥18 years old) presenting with CCS or NSTEACS with one or more study lesion(s) deemed appropriate (diameter stenosis 50-90%) for both pressure-wire and FFRangio physiologic assessment.

General Exclusion Criteria:

  1. Subject with ST-elevation (MI (STEMI) within 72 hours at time of study enrollment
  2. Prior coronary artery bypass graft (CABG) with patent grafts to the study vessel(s)
  3. Patients undergoing coronary physiologic assessment prior to possible CABG.
  4. The study vessel supplies a significant nonviable territory (e.g., prior transmural MI)
  5. Severe left sided valvular heart disease
  6. LVEF ≤ 30%
  7. Women who are pregnant or breastfeeding
  8. Patients with life expectancy <1 year life as estimated by treating physician.
  9. Subjects enrolled in other ongoing clinical studies.
