Background Software to compute angiography-derived fractional flow reserve (angio-FFR)
have been validated against pressure wire–derived fractional flow reserve (PW-FFR) with an …

Coronary lesions of intermediate severity often cause ischemia, and fractional flow reserve
(FFR)-guided revascularization for these coronary lesions is safe and effective. FFR derived …

Background An optimal system for interpreting fractional flow reserve (FFR) values derived
from CT (FFR CT) is lacking. We sought to evaluate performance of three FFR CT …

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

Background: This study aimed to introduce a novel optical coherence tomography-derived
fractional flow reserve (FFR) computational approach and assess the diagnostic …

Background Fractional flow reserve (FFR) based on computed tomography (CT) has been
shown to better identify ischemia-causing coronary stenosis. However, this current …

Objectives To compare outcomes of fractional flow reserve (FFR) to angiography (ANGIO)
guided percutaneous coronary intervention (PCI). Background The results of a recent …

Non-invasive fractional flow reserve measured by coronary computed tomography
angiography (FFR CT) has demonstrated a high diagnostic accuracy for detecting coronary …

Background A new CT-FFR technique with a “coarse-to-fine subpixel” algorithm has been
developed to generate precise lumen contours. The aim of this study was to assess the …

Aim Fractional flow reserve (FFR) allows for physiological definition of coronary lesion
severity but requires induction of maximal coronary circulation hyperemia with …
