Resting Full-cycle Flow Ratio (RFR) Versus Angiography to Guide Revascularization Strategy in Patients Undergoing Coronary Artery By-pass Grafting (CABG)
Different trials have shown that fractional flow reserve (FFR) could successfully guide revascularization in patients undergoing percutaneous coronary intervention (PCI). It is conceivable that a similar revascularization guidance could be useful also for surgical revascularization i.e. coronary by-pass graft (CABG).

Registry for Invasive and Non-invasive Anatomical Assessment and Outcome of Coronary Artery Anomalies
To mimic these conditions, dobutamine and volume challenge is used to invasively measure fractional flow reserve (FFR) during coronary angiography and is seen as the gold standard in assessing the hemodynamic relevance of ACAOS. We established a specialized interdisciplinary clinic for coronary artery anomalies including imaging specialists, invasive cardiologists and …

COronary and MICrocirculatory Measurements in Patients With Aortic Valve Stenosis.
Current guidelines recommend intra-coronary pressure measurement using either fractional flow reserve (FFR) or non-hyperemic pressure ratios (NHPR) for the assessment of intermediate coronary artery lesions before revascularization.

Effect of FFRCT-angio in Functional Diagnosis of Coronary Artery Stenosis
However, the stenosis severity is not closely corresponding with the hemodynamic significance in coronary arteries. As a result, fractional flow reserve (FFR) with pressure wire measurement was introduced to functionally assess the coronary stenosis. FFR is defined as the ratio of maximum blood flow distal to a stenotic lesion under …
