From 1978 to 1988, 300 patients with 616 aortocoronary venous bypasses underwent computed tomography (CT) 3 months after surgery, and angiography 1 day after CT. Both angiographic patency rate and CT patency rate were 75%. The sensitivity of the CT test for the detection of patent bypass grafts was 90 +/- 1.4%, the specificity of the CT test for the detection of occluded bypass grafts 72 +/- 3.6%. The observed predictive value of a patent CT test resulted in angiographically patent bypasses in 91 +/- 1.3%; the observed predictive value of an occluded CT test resulted in angiographically occluded bypasses in 71 +/- 3.6%. The low specificity for detecting occluded grafts is a considerable limitation of the technique. The pre-post-test patency ratio curve shows better predictive values for the CT test when there is a low pre-test likelihood of patency than when this is high. Patients with a high pre-test likelihood of occlusion, but who actually have patent coronary artery bypasses are most likely to benefit from this non-invasive test.
