Multicenter Registry for Angiography-Derived Quantitative Flow Ratio
Multicenter Registry for Diagnostic Accuracy of Angiography-Derived Quantitative Flow Ratio to Evaluate the Hemodynamic Significance of Coronary Artery Stenosis
Source: ClinicalTrials.gov · Last updated 17 Apr 2024
Brief summary (registry, in English)
1. to investigate the feasibility and diagnostic performance of contrast quantitative flow ratio (QFR) for identifying the functional significance of intermediate degree stenotic lesions in all-comer patients with coronary artery disease (CAD) including presentation of acute myocardial infarction (AMI) with non-culprit lesion. 2. to compare the changes of contrast QFR and fractional flow reserve (FFR) according to severity of percent diameter stenosis (%DS) 3. to evaluate prognostic implication of contrast QFR in comparison with FFR

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other
