Correlation of Pharmacological 99 mTcwSestamibi Myocardial Perfusion Imaging With Poststenotic Coronary Flow Reserve in Patients With Angiographically Intermediate Coronary Artery
Backgrnd The physiological assessment of angiographically intermediate-severity stenoses remains problematic. Functional measurements of poststenotic intracoronary Doppler coronary flow reserve can be performed in humans but have not been correlated with hyperemic myocardial perfusion imaging or angiographic data in this patient population. Method and Resus Thirty-three patients undergoing diag...
متن کاملLong-term clinical outcome after fractional flow reserve-guided treatment in patients with angiographically equivocal left main coronary artery stenosis.
BACKGROUND Significant left main coronary artery stenosis is an accepted indication for surgical revascularization. The potential of angiography to evaluate the hemodynamic severity of a stenosis is limited. The aims of the present study were to assess the long-term clinical outcome of patients with an angiographically equivocal left main coronary artery stenosis in whom the revascularization s...
متن کاملComparison of Fractional Flow Reserve Assessment With Demand Stress Myocardial Contrast Echocardiography in Angiographically Intermediate Coronary Stenoses.
BACKGROUND Real-time myocardial contrast echocardiography (RTMCE) directly measures capillary flow (CBF), which in turn is a major regulator of coronary flow and resistance during demand or hyperemic stress. Although fractional flow reserve (FFR) was developed to assess the physiological relevance of an epicardial stenosis, it assumes maximal microvascular vasodilation and minimal resistance du...
متن کاملSignificance of Intermediate Values of Fractional Flow Reserve in Patients With Coronary Artery Disease.
BACKGROUND The fractional flow reserve (FFR) value of 0.75 has been validated against ischemic testing, whereas the FFR value of 0.80 has been widely accepted to guide clinical decision making. However, revascularization when FFR is 0.76 to 0.80, within the so-called gray zone, is still debatable. METHODS AND RESULTS From February 1997 to June 2013, all patients with single-segment disease an...
متن کاملارتباط TFC) TIMI Frame Count) با کسر ذخیره جریانی (FFR) در بیماران مبتلا به تنگی متوسط عروق کرونر که تحت آنژیوگرافی کرونر قرار می‌گیرند
Background and Objective: Thrombolysis in myocardial infarction (TIMI) frame count (TFC) is an objective and quantitative index of coronary flow, and myocardial fractional flow reserve (FFR) is a lesion-specific index for epicardial coronary stenosis. Currently, FFR is the most valid tool for decision making in coronary interventions. However, it incurs relatively high costs and it is not reimb...
