Revascularization in stable ischemic heart disease (SIHD) is indicated in patients on optimal medical therapy with angina and/or demonstrable ischemia and a significant stenosis in one or more epicardial coronary arteries.

Angiography alone, however, often cannot accurately determine the hemodynamic significance of coronary lesions, particularly those of intermediate stenosis severity. A lesion may appear significant on coronary angiography but may not have functional significance. PCI of functionally insignificant coronary artery lesions may have serious consequences; therefore, judicious decision-making in the cardiac catheterization laboratory is indicated.

For this reason, it is becoming increasingly important to show that a stenosis is capable of inducing myocardial ischemia prior to intervention. Fractional flow reserve (FFR) is a well-validated evidence-based tool to objec...
