ABSTRACT
Objective To investigate the accuracy of three-dimensional reconstruction coronary angiography with CardiOp-B system in the evaluation of coronary artery stenosis, and make comparison with conventional quantitative coronary angiography(QCA). Methods The imaging data of 33 patients (39 vessel segments) who underwent coronary angiography and received interventional therapy were collected. The vessel diameter, vessel area, diameter of reference vessel rate of stenosed area and lesion length detected by three-dimensional reconstruction coronary angiography and QCA were compared. Results There was no significant difference in the detected minimal vessel diameter, minimal vessel area, diameter of reference vessel, rate of stenosed area and lesion length between three-dimensional reconstruction coronary angiography and QCA in these 39 vessel segments (P > 0.05), while the lesion length detected by three-dimensional reconstruction coronary angiography was significantly longer than that detected by QCA(P < 0.05). Conclusion Three-dimentional reconstruction of coronary angiography with CardiOp-B system demonstrates higher accuracy in the quantitative analysis of coronary artery stenosis compared with conventional QCA.
