5 de jun. de 2023 · The detection and characterization of coronary artery stenosis and atherosclerosis using imaging tools are key for clinical decision-making in patients with known or suspected coronary...
30 de nov. de 2021 · One of the key issues during stenosis evaluation is the quantification of the degree of stenosis. This may be performed either visually (visual estimation–VE) or using dedicated software packages for quantitative coronary angiography (QCA) to estimate the degree of diameter stenosis (DS).
21 de may. de 2013 · Conventional coronary angiography (CCA) is the gold standard for in vivo assessment of coronary arteries. The diagnostic accuracy of CCA is affected by many variables, including the orientation of the heart, angle selection for cardiac planes, and shape of the lesions.
7 de jul. de 2017 · It is noteworthy that for comparable coronary stenosis assessed with angiography FFR was significantly different according to the presence of age–sex 38 and diabetes mellitus. Those factors seem to be involved in coronary microvascular disease.
28 de dic. de 2021 · Volume of contrast and flow are the same of standard views. As for native CA, the ostium, body, and distal anastomosis should be interrogated during bypass graft angiography. Two orthogonal views of each segment should be obtained.
29 de abr. de 2020 · Coronary artery disease (CAD) is one of the leading causes of morbidity and mortality worldwide. 1 An accurate diagnostic assessment of CAD is pivotal in the management and clinical outcomes of patients. Both quantitative and hemodynamic assessments of coronary stenoses are vital in the prognostic stratification and management of patients with CAD.
30 de abr. de 2013 · Using quantitative coronary angiography (QCA) improved our ability to more accurately estimate the percent stenosis of a lesion and its length, which contribute to resistance to blood flow. 8 Although this technique is a well-validated tool for accurately and reproducibly defining coronary lesion severity, these validations were done mostly in t...
