Introduction: The presence and extent of myocardial ischemia are the major determinants of
prognosis in patients with coronary artery disease (CAD). Unlike coronary angiography …

Cardiovascular diseases represent the number one cause of death in the world, including
the most common disorders in the heart's health, namely coronary artery disease (CAD) …

The quantitative flow ratio (QFR) is a novel angiography-based computational method
assessing functional ischemia caused by coronary stenosis. This study aimed to evaluate …

Background. Fractional flow reserve (FFR), as a functional measurement of coronary
stenosis, is recommended for guiding revascularization in intermediate coronary lesions …

To date, the major focus of diagnostic modalities and interventions to treat coronary artery
disease has been the large epicardial vessels. Despite substantial data showing that …

Background: Invasive fractional flow reserve (FFRINV) is the standard technique for
