Abstract
Aim. The aim of this retrospective study was to evaluate capabilities of cardiac CT in patients with CABG (coronary artery bypass graft) and compare the accuracy of 16- (16DCT) and 64- (64DCT) detector-row CT in detecting significant stenosis of CABG. Method. A total of 250 patients with 774 bypasses underwent CT-angiography with ECG synchronization (152 patients on 16DCT, 98 patients on 64DCT). We evaluated patency and presence of significant stenosis (> 50%) and subsequently compared results of CT and invasive coronary angiography (ICA). Results. Altogether 583 bypasses were patent and 191 were occluded, 57 bypasses showed a stenosis greater than 50%. In 181 patent CABG assessed by both methods (MDCT and ICA), the results were compared. Sensitivity and specificity of 64DCT (90,4% and 98,1%) was higher than of 16DCT (84,6% and 95,8%). Conclusion. CT-angiography is feasible method for examination patients with CABG. 64DCT shows higher accuracy than 16DCT in detection of significant stenosis.
