Abstract:
Objective To investigate the diagnostic accuracy of 3-dimensional reconstruction(3DR) coronary angiography in the evaluation of coronary artery disease compared with conventional quantitative coronary angiography with IVUS result as the reference standard.Methods Twenty vessel segments in nineteen patients who underwent coronary angiography and IVUS were studied.With the IVUS result as the reference standard,the 3D reconstruction images and the single plane(2D) images of each angiograph were retrospectively studied and compared.Results In all the 20 segments,the minimal vessel diameter/area rate of the stenosed vessels and the reference vessels,and the minimal cross-sectional stenosis rate had no significant differences among the conventional 2D angiograph the 3DR angiograph and the IVUS results.According to the IVUS results,all the 20 vessel/segments were further divided into two groups which were:the eccentric stenosis group(n=7) and the centripetal stenosis group(n=13).In the centripetal stenosis group,all the angiographic parameters detected by the three methods had no statistical difference.In the eccentric stenosis group,the 3DR angiograph showed more consistent results as detected by IVUS compared with the 2D angiograph in terms of cross-sectional stenosis rate.Conclusion Three dimentional reconstruction of coronary angiography showed higher accuracy in the quantitative analysis of coronary artery stenosis compared with conventional coronary angiography,especially in eccentric stenosis.
