Abstract Objective: To detect left ventricular function before and after coronary artery bypass grafting in patients with coronary artery disease with multi slice spiral CT (MSCT) and to evaluate the treatment effect after CABG. Methods: A retrospective analysis of 38 patients (86 branches of bridging vessels) was performed by Ejection-Fraction software, volume rendering (VR) and multiplanar reformation (MPR). The changes of left ventricular function before and after coronary artery bypass graft surgery were analyzed, and the plaque formation and restenosis in the bridge were observed. Results: Multi slice spiral CT showed that 8 patients (8.1%) had restenosis caused by intravascular thrombosis, and 2 (2.3%) were completely obliterate. Postoperative left ventricular ejection fraction was significantly improved compared with that before operation (44.13 + 8.52 VS 39.26 + 7.46, P < 0.05). The change rate of left ventricular function index EF was 10.79 + 7.81 after operation, and 8 cases (total 9) had stenosis of bridge vessel, and the rate of change of EF was 6.87 + 4.71. Conclusion: Multi slice spiral CT can clearly observe the bridge vessels and detect left ventricular function at the same time, so as to evaluate the curative effect of coronary artery bypass grafting. It is a reliable examination method.
