Significats de fractional flow en anglès

The clinical use of fractional flow reserve in the culprit vessel may be preserved in selected patents with NSTEMI.

Background: The use of fractional flow reserve in patients with non-ST-segment-elevation myocardial infarction (NSTEMI) is a controversial issue.

Purpose of review: The role of fractional flow reserve to guide revascularization in patients with stable angina is well established.

Background: Assessment of stenosis severity with fractional flow reserve (FFR) requires that coronary resistance is stable and minimized.

Objectives: To investigate the relationship between classic SYNTAX and functional SYNTAX score guided by fractional flow reserve (FFR).

Data were analysed using Fermi and DP modeling against invasive coronary angiography and fractional flow reserve, acquired in all subjects.

Objectives: This study sought to evaluate the effects of fractional flow reserve (FFR) measurement variability on FFR-guided treatment strategy.

Background: Inducing both maximal and steady-state coronary hyperemia is of clinical importance to take full advantage of fractional flow reserve measurements.

His coronary angiogram showed 60% angiographic but hemodynamically insignificant stenosis by fractional flow reserve in the left anterior descending artery.

DILEMMA score (DS) is a validated angiographic functional scoring tool that correlates with fractional flow reserve and instantaneous wave-free ratio.

We appraised the diagnostic accuracy of IVUS-derived MLA compared with the fractional flow reserve (FFR) to assess intermediate coronary stenosis.

Background: A simplified formula to calculate the predicted fractional flow reserve (FFR) in sequen-tial coronary stenosis without balloon inflation is hereby proposed.

Previous cases have demonstrated changes in fractional flow reserve in a donor collateral vessel after PCI to a chronic total occlusion (CTO).

Objectives The fractional flow reserve (FFR) is an index of the severity of coronary stenosis that has been clinically validated in several studies.

Methods: To compare the fractional flow reserve between both internal thoracic arteries and saphenous vein grafts, 43 bypass grafts were studied 6 months after revascularization.

Fractional flow reserve is an established functional index of coronary blood flow.
