    The major epicardial coronary arteries (left main trunk, left anterior descending, left circumflex branches, and right coronary artery) were visually inspected with respect to their origin and course, and cut transversely at 2-mm intervals to the severity of artery stenosis by 2 experienced pathologists, using American Heart Association 15 ...

    For LAD and LAD/diagonal bifurcation visualization the cranial views are most useful. Overall, if there is not a significant limitation on contrast utilization, standard 'around the world' angiography using a selection of the following angiographic views will document left coronary anatomy.

    7 de jul. de 2017 · Methods and Results—. In 1382 coronary stenoses (1104 patients), percent diameter stenosis by visual estimation (DS VE) and by quantitative coronary angiography (DS QCA) was compared with FFR. Patients were divided into 4 subgroups, according to the presence of RFs, and the relationship between DS VE, DS QCA, and FFR was analyzed.

    mended views frequently resulted in more foreshortening than computer-generated optimal views, which had only 0.5% 6 1.2% foreshortening with < 2% overlap for the same 156 segments. Optimal views differed from the operator-selected working views by ≥ 108 in over 90% of vessels and frequently occurred in entirely different imaging quad-rants.

    1 de oct. de 2018 · Purpose. The present study investigated the diagnostic accuracy and clinical implications of moderate stenosis (50–69%, Coronary Artery Disease Reporting and Data System, grade 3) on coronary computed tomography angiography (CCTA), compared with invasive coronary angiography (ICA).

    1 de nov. de 2021 · Summary. Emerging evidence shows that atherosclerotic plaque burden, and not stenosis per se, is the main driver of ASCVD risk in patients with CAD. This information challenges the current paradigm of selecting patients for intensive secondary prevention measures based primarily on the presence of obstructive CAD.
