It has been demonstrated that the coronary artery anomalies (CAAs) are generally asymptomatic. However, some cases can cause severe life threatening events. As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative to invasive coronary angiography for the evaluation of coronary anatomy, the prevalence of CAAs in CCTA may more closely reflect the true prevalence in the general population. So we aimed to review and determine the prevalence of CAAs and variants retrospectively in patients who underwent CCTA at our center.
Reports of 1802 patients who underwent CCTA at the radiology department of our university hospital were traced for CAAs. At least two independent investigators reviewed the images, which were selected for further assessment prior to final classification.
One hundred and fifty two anomalies in 152 patients (8.44 %) were encountered. Origin of any coronary artery from the pulmonary trunk in 1 (0.06 %), origin of LMCA from right sinus in 1 (0.06 %), origin of right coronary artery (RCA) from left sinus in 5 (0.28 %), origin of left anterior descending artery (LAD) from right sinus in 2 (0.11 %), origin of circumflex branch (RCx) of LMCA from right sinus in 6 (0.33 %), origin of RCx from RCA in 4 (0.22 %), origin of any coronary artery from the ascending aorta in 2 (0.11 %), split RCA in 5 (0.28 %), RCx and left marginal artery from the first diagonal artery in 1 (0.06 %), myocardial bridging in 123 (6.83 %) and fistula in 2 (0.11 %) were detected as CAAs.
The prevalence of CAAs observed in this study was similar to the literature. CCTA can clearly visualize the anomalous origin, course and termination of the coronary artery.
已证实冠状动脉异常（CAA）通常无症状。然而，一些病例可导致严重的危及生命的事件。由于冠状动脉计算机断层扫描血管造影（CCTA）已成为用于评估冠状动脉解剖结构的侵入性冠状动脉造影的非侵入性替代方法，CCTA中CAA的患病率可能更准确地反映普通人群中的真实患病率。因此，我们旨在回顾并确定在我们中心接受CCTA的患者中CAA和变异的回顾性患病率。
追踪我校医院放射科1802例接受CCTA患者的报告，以查找CAA。至少两名独立研究人员对图像进行了审查，这些图像在最终分类之前被选作进一步评估。
在152例患者中发现了152处异常（8.44%）。其中，1例（0.06%）冠状动脉起源于肺动脉干，1例（0.06%）左主干（LMCA）起源于右窦，5例（0.28%）右冠状动脉（RCA）起源于左窦，2例（0.11%）左前降支（LAD）起源于右窦，6例（0.33%）LMCA的回旋支（RCx）起源于右窦，4例（0.22%）RCx起源于RCA，2例（0.11%）任何冠状动脉起源于升主动脉，5例（0.28%）RCA分支，1例（0.06%）RCx和左缘支起源于第一对角支，123例（6.83%）心肌桥，2例（0.11%）瘘管被检测为CAA。
本研究中观察到的CAA患病率与文献报道相似。CCTA可以清晰地显示冠状动脉的异常起源、走行和终止。
