Abstract Purpose of Review Three-dimensional quantitative coronary angiography-based
methods of fractional flow reserve (FFR) derivation have emerged as an appealing …

Intermediate coronary artery stenosis, defined as visual angiographic stenosis severity of
between 30–70%, is present in up to one quarter of patients undergoing coronary …

Over the last decade, steady progress has been made in the ability to assess coronary
stenosis relevance by merging computerised analyses of angiograms with fluid dynamic …

Background Quantitative flow ratio (QFR) is a novel angiography-derived index aimed to
assess the functional relevance of coronary stenoses without pressure wires and adenosine …

AIMS: We evaluate feasibility and reproducibility of post hoc quantitative flow ratio (QFR)
measurements and their prognostic predictive power during long-term follow-up. METHODS …

Cumulative evidence has shown that coronary revascularization should be guided by
functional significance of coronary lesions. Fractional flow reserve (FFR) is the gold standard …

Purpose Quantitative flow ratio (QFR) is a recently developed image-based index for the
assessment of borderline coronary artery disease. We sought to investigate a correlation …

Results Forty-four patients with 110 intermediate coronary lesions were enrolled. Mean
baseline Pd/Pa was 0.93±0.05. Mean cFFR value was similar to FFR value (0.83±0.09 vs …

Quantitative flow ratio (QFR) is a new angiography-based coronary physiology tool aimed to
evaluate functional relevance of intermediate coronary lesions. Aim of the study is to assess …
