Diagnostic performance of pressure drop coefficient in relation to fractional flow reserve and coronary flow reserve.
OBJECTIVES AND BACKGROUND Functional assessment of coronary lesion severity during cardiac catheterization is conducted using diagnostic parameters like fractional flow reserve (FFR; pressure derived) and coronary flow reserve (CFR; flow derived). However, the complex hemodynamics of stenosis might not be sufficiently explained by either pressure or flow alone, particularly in the case of inter...
متن کاملFractional flow reserve and complex coronary intervention.
This paper aims to provide a short overview of the theoretical background for coronary pressure-derived fractional flow reserve (FFR) index and to focus on its clinical applicability in complex coronary intervention.
متن کاملCoronary pressure measurement and fractional flow reserve.
The shortcomings of coronary arteriography to assess the physiological significance of coronary stenoses have been recognised for decades ; therefore, the importance of additional physiological techniques is beyond doubt. One of the currently available physiological techniques is coronary pressure measurement, which has emerged over the past few years as a major step forward in the invasive ass...
متن کاملRole of variability in microvascular resistance on fractional flow reserve and coronary blood flow velocity reserve in intermediate coronary lesions.
BACKGROUND Fractional flow reserve (FFR) and coronary blood flow velocity reserve (CFR) represent physiological quantities used to evaluate coronary lesion severity and to make clinical decisions. A comparison between the outcomes of both diagnostic techniques has not been performed in a large cohort of patients with intermediate coronary lesions. METHODS AND RESULTS FFR and CFR were assessed...
متن کاملComprehensive assessment of coronary fractional flow reserve
Fractional flow reserve (FFR) is considered nowadays as the gold standard for invasive assessment of physiologic stenosis significance and an indispensable tool for decision-making in coronary revascularization. Robust studies have shown that FFR is more effective in accurately identifying which lesions should be stented, and revascularization guided by FFR improves the outcome of coronary arte...
