Local Recommendations of Downstream Diagnostic Work-Up of Patients After Coronary CTA and FFRCT Testing Between May 2014 and April 2015

Test OutcomeDownstream Diagnostic Test
Coronary CTA
High riskICA
 Diagnostic conclusiveIntermediate riskFFRCT
Low riskNo additional testing§
 Diagnostic inconclusiveMyocardial perfusion imaging
>0.80No additional testing§

CTA = computed tomography angiography; FFRCT = coronary computed tomography angiography–derived fractional flow reserve; ICA = invasive coronary angiography.

  • Patients with left main, 3-vessel disease, and/or high-grade proximal left anterior descending artery stenosis.

  • Patients with 1 or 2 intermediate coronary stenoses (lumen reduction 30% to 70%).

  • Patients with no coronary disease or with maximum coronary stenosis <30%.

  • § Optimal medical treatment was recommended. If coronary artery disease was present, statin, aspirin, and/or antianginal medication were generally prescribed or recommended via the general practitioner.
