Figure 1. Three-dimensional reconstruction of patent left and right internal mammary arteries, which can be seen on either side of the aorta. A larger saphenous vein graft to the obtuse marginal can be seen in the middle of the image with a stenosis in its mid-course Limitations CTCA is highly accurate at detecting stenoses in bypass grafts with sensitivity, specificity, negative and positive predictive values of 97%, 97%, 93% and 99%, respectively.3 The limitation of CTCA in patients with CABG is in the assessment of the native coronary arteries distal to the grafts and the coronary arteries that did not receive bypass grafts at the time of
