Abstract
The introduction of fractional flow reserve computed tomography (FFR-CT) that is performed from static coronary CT angiography datasets may open new horizons in the diagnostic management of patients with suspected coronary artery disease. FFR-CT has a high sensitivity and moderate specificity in identifying ischemia in intermediate coronary stenoses. It has been demonstrated that this technology has the potential to significantly reduce the number of invasive coronary angiograms and the rate of normal coronary angiograms that are not followed by an intervention. Furthermore, initial data indicate that FFR-CT may predict the hemodynamic effect of stenting and even of bypass surgery. Thus, FFR-CT, with its capacity to serve as an effective gatekeeper before invasive angiography and the option to virtually predict the success of revascularization, constitutes a completely new concept in managing patients with stable angina pectoris. Before this exciting technology can enter clinical practice, however, some evident limitations need to be overcome and significantly more data concerning accuracy and influence on clinical and economic outcome parameters need to be generated.
