CTICasesFractional flow reserve (CT-FFR) triage for coronary artery disease
Imaging findings
Coronary CTA shows calcified plaque and stenosis in the proximal coronary arteries. FFR assessment shows values greater than 0.80 distally, confirming hemodynamically non-significant disease.
Key takeaways
CT-derived FFR (FFR-CT) is a non-invasive tool to assess the hemodynamic significance of coronary artery lesions. An FFR value >0.80 across a stenosis indicates adequate flow, safely avoiding invasive catheterization.
