A Blind Self Controlled Multicenter Clinical Trial on the Effectiveness and Safety of Noninvasive Flow Reserve Score Analysis Software for Coronary Angiography
The gold standard group data is the clinical measured FFR (clinical gold standard) at the stenosis lesions. It is defined that when the coronary artery reaches the maximum congestion state, the pressure value at the distal end of the stenosis lesions is accurately measured by the guide wire with a …

Registry for Invasive and Non-invasive Anatomical Assessment and Outcome of Coronary Artery Anomalies
The possible presence of an interarterial/intramural course is the primary cause for an oval proximal vessel shape and/or proximal vessel narrowing, which may lead under stress conditions to a "dynamic compression" of the vessel (compared to "fixed" stenosis in coronary artery disease). To mimic these conditions, dobutamine and volume challenge …

Effect of FFRCT-angio in Functional Diagnosis of Coronary Artery Stenosis
Coronary CT angiography (CTA) or invasive coronary angiography (CAG) is usually performed to evaluate the severity of coronary stenosis depending on the probability of CAD. However, the stenosis severity is not closely corresponding with the hemodynamic significance in coronary arteries.
