Originally published7 Jan 2003https://doi.org/10.1161/01.CIR.0000048090.33442.C8Circulation. 2003;107:147–148A 56-year-old man presented to our hospital because of chest pain on effort. Conventional coronary angiography revealed high-grade stenosis in the proximal and distal portions of the left anterior descending branch (LAD). We therefore performed percutaneous transluminal coronary angioplasty with metallic stent implantation at the stenotic sites. Four months after the stent placement, ECG-gated enhanced multislice computed tomography (CT) (Light Speed Ultra, General Electric) was performed with a 1.25-mm slice thickness, helical pitch 3.25, to evaluate the coronary artery lumen for restenosis at the stent implantation sites. After intravenous injection of 100 mL of iodinated contrast material (350 mgI/mL), CT scanning was performed with retrospective ECG-gated reconstruction. After acquisition, volume data were extracted from end-diastole, and volume-rendering images were generated (M900 Zio). In the axial source image and cut-plane volume rendering image, the patency of the coronary arterial lumen of the proximal portion of the LAD surrounded by the metallic stent (arrows, Figure 1, arrows) was observed without any artifact from the metallic stent. The next day, conventional coronary angiography showed no significant luminal stenosis of the proximal (Figure 2, arrow) and distal portions of the LAD. Download figureDownload PowerPointFigure 1. Axial source image (A) and volume rendering (VR) image (B) of the proximal portion of the LAD using end-diastolic data from enhanced multislice CT. Arrows show the stent located in the proximal portion of the LAD. A, The axial source image shows the patent coronary arterial lumen surrounded by the metallic stent (arrow). B, Cut-plane VR image from the superior left anterior view shows the vessel lumen surrounded by the metallic stent (arrow). The color curves were set to represent the vessel lumen filled with contrast material as yellow and the metallic stent as white. The metallic stent with CT numbers above those of the contrast-enhanced coronary artery lumen could be distinguished by VR, and the patency of the lumen surrounded by the metallic stent appeared to be maintained. The arrowhead in the VR image indicates the stent located in the distal portion of the LAD. Patency of the coronary artery lumen of the distal portion of the LAD could not be evaluated.Download figureDownload PowerPointFigure 2.
