Accurate determination of aortocoronary bypass graft patency is still dependent on angiography, an invasive procedure. A non-invasive method, easily performed, repeatable and without special risks, visualizing the anatomy and providing direct information on graft patency would be very useful in the postoperative control of patients after bypass graft surgery. In this aspect, computed tomography (CT) has been reported to represent an ideal tool [1–12]. However, merits and limits of this method need to be defined, since in the studies published so far, the number of investigated grafts are often small and angiographic controls of the results are not always available. Therefore, in a consecutive series of patients who underwent postoperative coronary angiography due to persistent or recurrent angina pectoris, CT scanning was also performed for assessment of bypass graft patency in close temporal relation to angiography. |
