Visualization of the improvement of myocardial perfusion after coronary intervention using motorized fractional flow reserve pullback curve
This study aimed to evaluate the feasibility and utility of using motorized pullback of the pressure guidewire to provide a graphic assessment and prediction of the benefits of coronary intervention. Fractional flow reserve (FFR) measurements were performed with motorized pullback imaging in 20 patients who underwent successful percutaneous coronary intervention (PCI) of the left anterior desce...
متن کاملDecrease of fractional flow reserve shortly after percutaneous coronary intervention.
BACKGROUND The aim of the present study was to quantitatively assess the physiological acute recoil after percutaneous coronary intervention (PCI), and to determine the relation between it and target lesion revascularization (TLR) in the chronic phase. METHODS AND RESULTS This study evaluated 76 patients who underwent elective PCI between May 1997 and December 2001: plain old balloon angiopla...
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 کاملValidation of collateral fractional flow reserve by myocardial perfusion imaging.
BACKGROUND Collateral fractional flow reserve (FFR(coll)) is an index to quantify collateral blood flow, derived from coronary pressure measurements. Although well defined theoretically, its direct validation by myocardial perfusion imaging has not been established so far. Validating this index by myocardial perfusion imaging is the main aim of this study. METHODS AND RESULTS Twenty-four cons...
متن کاملThe value of myocardial perfusion imaging with Tc-99m MIBI for the prediction of perfusion improvement after percutaneous transluminal coronary angioplasty
Introduction: Percutaneous transluminal coronary angioplasty (PTCA) is an effective method for revascularizing of stenotic coronary vessels. Lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. Introduction of a noninvasive metho...
