Computed tomography for detection and postoperative imaging of the left anterior descending artery occlusion incompletely visualized by conventional angiography.

Fig. 1. LAO angiographic view failing to visualize the accurate course of distal LAD (black arrowheads) (A). CT curved multiplanar reconstruction demonstrating clearly the distal segment of LAD (B). Cx: circumflex artery; Dg: diagonal branch; LAD: left anterior descending artery. Fig. 2. CT sagittal maximum intensity projection performed 12 months after surgical revascularization confirmed good patency of the left internal mammary artery jump graft to the LAD (A). 3D volume-rendered reconstruction showing patent arterial jump graft to the LAD, first diagonal branch and second obtuse marginal branch (B). 3D volume-rendered reconstructions demonstrating non-stenotic anastomotic site to the LAD (C and D). LAD: left anterior descending artery; LIMA: left internal mammary artery.
