Your provider uses an instrument to take blood pressure readings on both sides of a blockage inside your coronary artery. The equipment uses these readings to calculate your fractional flow reserve. See more Your provider may ask you to stop taking certain medicines, especially blood thinners, several days before your test. Also, don’t eat or … See more Your healthcare provider will: 1. Inject a local anesthetic into your skin. 2. Insert a needle in your arm, neck or groin. 3. Use the needle to thread a catheter into your artery. 4.

The capacity of the two indexes to predict the hemodynamic outcome after stenting will be compared. Goals of the study are:

WebFractional flow reserve (FFR) is an invasive index of the functional severity of a stenosis determined from coronary pressure measurement during coronary catheterization. A 0.014-in pressure wire is advanced, after calibration, into the relevant coronary segment. It is positioned distally to the stenosis. Adenosine is administered intravenously ...

The decision to perform a percutaneous coronary intervention (PCI) is usually based on angiographic results alone. Angiography can be used for the visual evaluation of the inner diameter of a vessel. In ischemic heart disease, deciding which narrowing is the culprit lesion is not always clear-cut. Fractional flow reserve can provide a functional evaluation by measuring the pressure decline caused by a vessel narrowing. WebAn FFR lower than 0.75-0.80 is generally considered to be associated with myocardial ischemia.7. FFR < 0.75 was validated against the 3 gold standard tests to correlate with ischemia with 100% specificity. FFR between 0.75 and 0.80 may indicate ischemia. FFR > 0.80 is highly likely to be non‑ischemic.
