Comprehensive Assessment of Coronary Artery Stenoses

چکیده
Methods We investigated 79 patients with stable angina pectoris who underwent both 64-slice or dual-source CTCA and FFR measurement of discrete coronary stenoses. CTCA and conventional coronary angiography (CCA), and QCT and quantitative coronary angiography (QCA), were performed to determine the severity of a stenosis that was compared with FFR measurements. A significant anatomical or functional stenosis was defined as 50% diameter stenosis or an FFR 0.75. Stented segments and bypass grafts were not included in the analysis.

Combined CT coronary angiography and stress myocardial perfusion imaging for hemodynamically significant stenoses in patients with suspected coronary artery disease: a comparison with fractional flow reserve.
OBJECTIVES We sought to determine the accuracy of combined coronary computed tomography angiography (CTA) and computed tomography stress myocardial perfusion imaging (CTP) in the detection of hemodynamically significant stenoses using fractional flow reserve (FFR) as a reference standard in patients with suspected coronary artery disease. BACKGROUND CTP can be qualitatively assessed by visual...
متن کامل“ Resistance in the cath lab ” : the utility of hyperemic stenosis resistance in the functional assessment of coronary artery disease
Percutaneous coronary intervention (PCI) guided by functional assessment of coronary stenoses, either noninvasively or invasively, by selective treatment of ischemia-inducing stenoses confers improved cardiovascular outcomes. We present the case of a 56-year-old man with multivessel coronary artery disease, who underwent PCI guided by invasive physiological assessment using both single modality...
متن کاملAccuracy of MSCT Coronary Angiography with 64 Row CT Scanner—Facing the Facts
Improvements in multislice computed tomography (MSCT) angiography of the coronary vessels have enabled the minimally invasive detection of coronary artery stenoses, while quantitative coronary angiography (QCA) is the accepted reference standard for evaluation thereof. Sixteen-slice MSCT showed promising diagnostic accuracy in detecting coronary artery stenoses haemodynamically and the subseque...

The purpose of this study was to investigate the value of a respiratory-gated three-dimensional (3D) magnetic resonance angiographic technique (MRCA) in identifying coronary arteries in healthy volunteers and patients with proximal coronary artery stenoses and to compare the results of the navigator echo technique in the assessment of coronary artery stenosis with conventional coronary angiogra...
متن کاملThe effect of turbulence model on predicting the development and progression of coronary artery atherosclerosis
A severe case of stenosis in coronary arteries results in turbulence in the blood flow which may lead to the formation or progression of atherosclerosis. This study investigated the turbulent blood flow in a coronary artery with rigid walls, as well as 80% single and double stenoses on blood flow. A finite element-based software package, ADINA 8.8, was employed to model the blood flow. The hemo...
