Hace 1 día · (LMT: 50% stenosis, LAD proximal: 90% stenosis, OM2: 80% stenosis, RCA distal: 90% stenosis) Open in new tab Download slide The patient was positioned by elevating in a 30° to 40° right lateral decubitus position to facilitate a widened intercostal space.
Hace 4 días · LAD and Cx/RCA arteries were simulated with separate model parameters for the relationship between proximal reference area and microvascular conductance. We achieved the best summary agreement between observed and simulated flow with reference (at a standardized reference lumen size of 10 mm 2 ) conductance values of 0.064 mL/s/mmHg for the LAD and 0.043 mL/s/mmHg for the Cx/RCA.
Hace 3 días · Lesion-specific CT-FFR was measured at 2 cm away from the plaque. CT-FFR ≤ 0.8 was defined as hemodynamically significant stenosis. Definite plaque was firstly detected in left main coronary artery (LM), left anterior descending artery (LAD), left circumflex artery (LCX) and RCA.
Hace 3 días · According to Oikonomou et al. , FAI was calculated for perivascular fat in the proximal segment of 4 cm; CT-FFR based on three-dimensional CFD combined with deep learning was presented in the form of a colored coronary tree, with different colors denoting different CT-FFR values, and the measurement site was located 2 cm posterior to the stenosis of the target lesion.
Hace 2 días · Atherosclerosis was defined as: 1. presence of a plaque in any of 18 coronary segments, 2. presence of a vessel stenosis of ≥50 % in any of the segments, 3. presence of a plaque in at least four of the segments, and 4. presence of a ≥ 50 % stenosis in the left main artery (LM), proximal left descending artery (LAD) or three vessel disease ...
Hace 2 días · They were defined as revascularization at the previously treated segment from 5 mm proximal to the stent to 5 mm distal to the stent with ≥70% diameter stenosis and at least 1 of the following: 1) recurrence of angina; 2) positive noninvasive test result; or 3) positive invasive physiological test result.
Hace 5 días · Initial coronary angiography (CAG) reveals severe diffuse triple-vessel coronary artery disease (A, B). The proximal part of the right coronary artery (RCA) reveals chronic total occlusion (arrow), the proximal left ascending artery (LAD) reveals subtotal occlusion (arrowhead), and the distal part of the left circumflex artery (LCX) reveals 99% diffuse stenosis.
