Fractional 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 کاملPrediction of fractional flow reserve with angiographic DILEMMA score
OBJECTIVE Angiographic assessment of stenosis has limited predictive value for functionally significant lesions compared with fractional flow reserve (FFR). The recently developed angiographic DILEMMA score, which consists of minimal lumen diameter (MLD), lesion length (LL) and Bypass Angioplasty Revascularization Investigation (BARI) Myocardial Jeopardy Index (MJI) was found to have diagnostic...
متن کاملLetter to the editor: “A novel angiographic fractional flow reserve”
TO THE EDITOR: We read with great interest the article “Quantification of absolute coronary flow reserve and relative fractional flow reserve in a swine animal model using angiographic image data,” published in the American Journal of Physiology-Heart and Circulatory Physiology (5). Fractional flow reserve (FFR) is an epicardial lesion-specific parameter to determine the functional coronary ste...
متن کاملEnd-diastolic fractional flow reserve: comparison with conventional full-cardiac cycle fractional flow reserve.
BACKGROUND Diastolic fractional flow reserve (dFFR) has been shown to be highly sensitive for detection of inducible myocardial ischemia. However, its reliance on measurement of left-ventricular pressure for zero-flow pressure correction, as well as manual extraction of the diastolic interval, has been its major limitation. Given previous reports of minimal zero-flow pressure at end-diastole, w...
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...
