Coronary angiography is an imperfect tool for assessing the functional significance of lesions: while this may be determined non-invasively using myocardial perfusion scintigraphy or stress echocardiography, it is often not done. In these circumstances the coronary pressure-derived fractional flow reserve (FFR) serves as an alternative, lesion-specific means of assessing physiological importance.
FFR is an invaluable tool not only in determining whether a lesion is functionally significant and should be tackled, but it also ensures that the appropriate physiological outcome is obtained from coronary intervention.
