Case Report of First Angiography-Based On-Line FFR Assessment during Coronary Catheterization

الملخص EN

Fractional flow reserve (FFR), an index of the hemodynamic severity of coronary stenoses, is derived from hyperemic pressure measurements and requires a pressure-monitoring guide wire and hyperemic stimulus.

Although it has become the standard of reference for decision-making regarding coronary revascularization, the procedure remains underutilized due to its invasive nature.

FFRangio is a novel technology that uses the patient’s hemodynamic data and routine angiograms to generate a complete three-dimensional coronary tree, with color-coded display of the FFR values at each point along the vessels.

After being proven to be as accurate as invasive FFR measurements in an off-line study, this case report presents the first on-line application of the system in the catheterization lab.

Here too, a high concordance between FFRangio and invasive FFR was observed.

In light of the demonstrated capabilities of the FFRangio system, it should emerge as an important tool for clinical decision-making regarding revascularization in patients with coronary artery disease.
