Figure 5 Computed tomography angiography in a patient with 3 venous coronary artery bypass grafts. (A) Transaxial cross section showing the aortic anastomosis and a cross section of the mid-segments of the venous graft to the left anterior descending coronary artery (arrows). In addition, a cross section of the left circumflex graft is seen (arrowhead). (B) Transaxial 5-mm thick maximum intensity projection showing the aortic anastomosis of the right coronary artery bypass graft (double arrows). In addition, a cross section of the left anterior descending graft (larger arrow) and of the left circumflex graft (arrowhead) are visible. The proximal left coronary artery is seen, with a high-grade stenosis of the left main coronary artery proximal to the bifurcation (smaller arrow). The coronary arteries are of narrow lumen and have substantial calcification. (C) Curved multiplanar reconstruction of the venous graft to the right coronary artery (arrows). The double arrows indicate the anastomosis to the distal right coronary artery. (D) Three-dimensional reconstruction showing bypass graft to left anterior descending (larger arrow), to left circumflex (arrowhead), and to right coronary artery (smaller arrow).
