PURPOSE: Fractional flow reserve (FFR) is often performed to assess the severity of
coronary artery stenoses. However, the usefulness of measuring FFR when a noninvasive …

Background Visual angiographic assessment of intermediate coronary lesions is poor at
determining the functional significance. We sought to identify independent clinical and …

The impact of the fractional flow reserve (FFR) on clinical decision-making remains unclear
in daily practice. The CVIT-DEFER registry is a prospective multicenter registry enrolling …

The evidence for the use of cardiovascular magnetic resonance (CMR) as a first-line
diagnostic tool in patients with suspected coronary artery disease (CAD) has been solidified …

Background Randomized trials using measurement of fractional flow reserve (FFR) to guide
percutaneous coronary intervention (PCI) have demonstrated both safety and efficacy with …

Revascularization of coronary artery stenosis should be based on the objective evidence of
ischemia. It is common practice for physicians to make decisions on revascularization in the …

Objectives This study sought to assess the diagnostic performance of FFRangio (CathWorks,
Kfar Saba, Israel), an angiogram-derived fractional flow reserve (FFR) technology …

Fractional flow reserve (FFR) is an invasive physiologic index measured in the cardiac
catheterization laboratory to assess the functional significance of a coronary stenosis. It is …

This study determined the safety of deferring coronary revascularization based on a
fractional flow reserve (FFR) value≥ 0.75 in a series of consecutive unselected coronary …

It is well known that the apparent significant coronary stenosis on angiography sometimes
does not cause significant ischemia, and vice versa. For this reason, decision-making based …
