Fractional Flow Reserve: The Past, Present and Future
Revascularization of coronary artery stenosis should be based on the objective evidence of ischemia. It is common practice for physicians to make decisions on revascularization in the cardiac catheterization laboratory based on the results of angiography, despite the fact that angiographic information does not correlate well with the functional significance of a coronary lesion. Fractional flow...
متن کاملFractional Flow Reserve
Traditionally, coronary artery disease was assessed using coronary angiographic guidance. Significant lesions were determined by the coronary angiographer. However, interobserver variability showed a significant limitation of interpretation of coronary angiography. Stent deployment and apposition were also evaluated based on angiographic appearance only. Risk factors for stent thrombosis and in...
متن کاملHybrid Instantaneous Wave-Free Ratio–Fractional Flow Reserve versus Fractional Flow Reserve in the Real World
BACKGROUND The instantaneous wave-free ratio (iFR) is a novel method to assess the ischemic potential of coronary artery stenoses. Clinical trial data have shown that iFR has acceptable diagnostic agreement with fractional flow reserve (FFR), the reference standard for the functional assessment of coronary stenoses. This study compares iFR measurements with FFR measurements in a real world, sin...
متن کامل“Virtual” (Computed) Fractional Flow Reserve
Ma Fractional flow reserve (FFR) is the “gold standard” for assessing the physiological significance of coronary artery disease during invasive coronary angiography. FFR-guided percutaneous coronary intervention improves patient outcomes and reduces stent insertion and cost; yet, due to several practical and operator related factors, it is used in <10% of percutaneous coronary intervention proc...

n engl j med 372;1 nejm.org january 1, 2015 94 difference. The observed loss of FEV1 was neither a time-dependent nor a dose-dependent effect in the withdrawal group, as compared with the maintenance group. A difference of 38 ml between groups became apparent only after the final step of inhaled glucocorticoid withdrawal and did not change to a meaningful extent thereafter. Singanayagam et al. ...
