| 摘 要： | 目的 研究CardiOp-B冠状动脉造影三维(3D)重建系统分析冠状动脉狭窄病变的准确性,并与传统定量冠状动脉造影(QCA)进行对照分析研究.方法 收集接受冠状动脉造影并行介入治疗的33例患者(39处血管段)的影像资料.分析比较冠状动脉3D重建和QCA传统平面图像对靶病变管腔直径和面积、参考血管直径、面积狭窄率、病变血管长度的测量值.结果 39处病变3D重建和QCA两种测量方法所测得的最窄处管腔直径和面积、参考血管直径、面积狭窄率差异均无统计学意义(P>0.05);而3D重建组病变血管长度大于QCA组,且差异存在统计学意义(P<0.05).结论 与QCA相比,CardiOp-B冠状动脉造影3D重建定量系统能够更准确地重建并定量分析冠状动脉狭窄病变.

| 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. |
