Fractional Flow Reserve in Japanese Routine Clinical Practice.
nary artery bypass grafting (CABG) procedures. Another distinct point is the high penetration of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in Japan: 83% of the total PCI procedures performed in 2016 from the data of JROAD. This is a big advantage of Japanese-style intervention, because intravascular imaging has recently emerged as a critical modality for ac...
متن کاملStandardization of Fractional Flow Reserve Measurements.
Pressure wire-based fractional flow reserve is considered the standard of reference for evaluation of the ischemic potential of coronary stenoses and the expected benefit from revascularization. Accordingly, its application in daily practice or for research purposes has to be as standardized as possible to avoid technical or operator-related artifacts in pressure recordings. This document propo...
متن کاملImpact of Right Atrial Pressure on Fractional Flow Reserve Measurements: Comparison of Fractional Flow Reserve and Myocardial Fractional Flow Reserve in 1,600 Coronary Stenoses.
OBJECTIVES This study sought to assess the impact of a wide range of mean right atrial pressure (Pra) on fractional flow reserve (FFR) measurements. BACKGROUND FFR invasively assesses the ischemic potential of coronary stenoses. FFR is calculated as the ratio of mean distal coronary pressure (Pd) to mean aortic pressure (Pa) during maximal hyperemia. The Pra is considered to have little impac...
متن کاملDiagnostic accuracy of fractional flow reserve from anatomic CT angiography.
CONTEXT Coronary computed tomographic (CT) angiography is a noninvasive anatomic test for diagnosis of coronary stenosis that does not determine whether a stenosis causes ischemia. In contrast, fractional flow reserve (FFR) is a physiologic measure of coronary stenosis expressing the amount of coronary flow still attainable despite the presence of a stenosis, but it requires an invasive procedu...
متن کاملClinical applications of fractional flow reserve in bifurcation lesions
Percutaneous coronary intervention (PCI) for coronary bifurcation lesions has been associated with lower procedural success rates and worse clinical outcomes compared with PCI for simple coronary lesions. Angiographic evaluation alone is sometimes inaccurate and does not reflect the functional significance of bifurcation lesions. The fractional flow reserve (FFR) is an easily obtainable, reliab...
