ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the diagnostic accuracy in the assessment of coronary artery bypass grafts using 64 multi-slice computed tomography angiography (64-MSCTA) technology.</p><p><b>METHODS</b>There were 228 patients post coronary artery bypass grafting (CABG) underwent 64-MSCTA from July 2005 to April 2007. Thirty-one patients with 82 bypass grafts performed coronary angiography (CAG) because of angina or grafts lesion showed by 64-MSCTA.</p><p><b>RESULTS</b>All bypass grafts could be visualized by 64-MSCTA. Thirteen bypass graft occlusions and fourteen significant stenosis were detected by 64-MSCTA and confirmed by CAG. One venous grafts distal anastomosis was missed and another one was miss diagnosed as stenosis. One false negative and one false positive CT-finding resulted in a sensitivity of 93.3%, a specificity of 98.1%, a positive predictive value of 93.3%, a negative predictive value of 98.1% and an accuracy of 97.1% for grafts stenosis. As to the grafts lesion, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy for grafts occlusion were 96.4%, 98.1%, 96.4%, 98.1% and 97.6%, respectively.</p><p><b>CONCLUSION</b>64-MSCTA demonstrates high diagnostic accuracy in the assessment of graft patency and suitable for the follow-up of patients post CABG.</p>
