Introduction: The severity of a coronary artery lesion is traditionally assessed from the cine angiograms by the visual method. This study was done to find out how this method correlates with the automated computer quantification (ACQ) method from the digital angiograms.Methodology: 50 consecutive ...
New CAD was diagnosed when patients had either angiographic evidence of obstructive CAD on a CCTA (ie, >50% obstruction) and/or angiographic evidence of obstructive CAD on an invasive coronary angiogram (ie, >50% obstruction). If these data were not provided, new CAD was diagnosed if any ...
111 This technique could offer a virtual FFR using a simple coronary angiogram, deriving anatomical and functional lesion characteristics without the risk of the pressure wire. Additionally, coronary wall shear stress, computed using coronary angiography images, identifies area of plaque vulnerability and...
Emergency vs delayed coronary angiogram in survivors of out-of-hospital cardiac arrest: results of the randomized, multicentric EMERGE trial. JAMA Cardiol. 2022;7(7):700-707. doi:10.1001/jamacardio.2022.1416 ArticlePubMedGoogle ScholarCrossref 15. Kern KB, Radsel P, Jentzer ...
A total of 91 consecutive patients underwent both low-dose 64-slice CT calcium scoring scan as well as conventional angiography of the heart. The total CCS of abnormal coronary angiogram (n = 45) was 297.38 +/- 416.93, whereas that of normal coronary angiogram (n = 46) was 5.37 +/- ...
自2015年11月至2017年8月于心内科招募已行冠脉造影(Coronary angiography,CAG)指导冠脉支架植入的症状性冠心病患者44例。本研究已通过临床伦理委员会审批,招募的患者均已签署知情同意书。按已经制定的入选标准排除严重肾衰竭、血管炎、心肌炎和转移性恶性肿瘤患者12例。最终确定32例患者被纳入本研究,其中男性22例、女性...
[25]. Furthermore, in our center, patients with very high coronary artery calcium scores (as assessed by the clinical team on the day of the scan) were referred directly for an invasive X-ray coronary angiogram, without performing a contrast enhanced coronary CTA, in order to avoid ...
coronary angiography print; hidden biometric; filtered LBP; NCA; biometrics1. Introduction A coronary angiogram is one of the X-ray imaging techniques [1,2]. Coronary angiography is the gold standard diagnostic method of coronary artery disease (CAD) and CAD is the disease that causes the most...
Freeze frames from cine loops obtained during invasive coronary angiography were used for the analysis of the left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA). Assessment of coronary arteries was performed from two-dimensional angiograms. The left anterior ...
