Figure 1 A 54-Year-Old Patient With Unstable Angina 3 Years After 4-Vessel Bypass Grafting
Three-dimensional reconstructions demonstrate 4 patent bypass grafts in the anterior (A) and left lateral (B) projections. Invasive angiography confirmed patent saphenous vein grafts to the 1st diagonal branch (C) and 2nd obtuse marginal branch (D), as well as a patent radial artery graft to the 1st obtuse marginal branch (E) and a patient left internal mammary artery graft to the left anterior descending coronary artery (F).

Figure 2 A 73-Year-Old Male Patient With Stable Angina Undergoing Multislice Computed Tomography Angiography 15 Years After 5-Vessel Bypass Grafting
The 3-dimensional reconstruction (A) and invasive angiography (B to D) demonstrate an occluded saphenous vein graft to the diagonal branch at the aortic anastomosis site (A), a severely stenosed saphenous vein graft to the right coronary artery (B), a moderately stenosed saphenous vein jump graft to the 1st and 2nd obtuse marginal branches (C), and a left internal mammary graft to the left anterior descending coronary artery with a significant stenosis at the distal anastomosis site (D). Invasive angiography confirmed the multislice computed tomography findings (B to D).
