Quantification of absolute coronary flow reserve and relative fractional flow reserve in a swine animal model using angiographic image data.
Coronary flow reserve (CFR) and fractional flow reserve (FFR) are important physiological indexes for coronary disease. The purpose of this study was to validate the CFR and FFR measurement techniques using only angiographic image data. Fifteen swine were instrumented with an ultrasound flow probe on the left anterior descending artery (LAD). Microspheres were gradually injected into the LAD to...
متن کاملCORONARY FLOW RESERVE Digital subtraction angiographic imaging of coronary flow reserve
Recent studies have demonstrated that subjective assessment of the severity of coronary artery stenoses results in poor interobserver concordance and poor correlation with physiologic significance as determined by Doppler measurements of coronary flow reserve. Use of the coronary flow reserve as an integrated measure of the effect of stenosis geometry has been emphasized within the context of q...

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 کاملFractional flow reserve in acute coronary syndromes.
Little doubt exists about the outcome benefit of an invasive strategy in patients with an acute coronary syndrome (ACS). Yet, once the revascularization is performed, the treatment strategy of patients admitted with an ACS is not always as straightforward in daily clinical practice as indicated in guidelines. The reasons for this are at least three-fold. First, a sizable proportion of patients ...
