The aim of this study was to evaluate the coronary arteries in patients undergoing thoracic CT angiography for congenital heart disease, to determine the frequency of detection of coronary artery anomalies in congenital heart diseases, and to determine which type of anomaly is more common in which disease.
In our investigation, a 128-detector multidetector computed tomography machine was used to perform thorax CT angiography. The acquisition parameters were set to 80-100 kVp based on the patient's age and mAs that the device automatically determined based on the patient's weight. During the examination, an intravenous (IV) nonionic contrast material dose of 1-1.5 mL/kg was employed. An automated injector was used to inject contrast material at a rate of 1.5-2 mL/s. In the axial plane, 2.5 mm sections were extracted, and they were rebuilt with 0.625 mm section thickness.
Between October 2022 and May 2024, 132 patients who were diagnosed with congenital heart disease by echocardiography and underwent Thorax CT angiography in our department were retrospectively evaluated. Of the evaluated patients, 32 were excluded with exclusion criteria such as patients being younger than 3 months, older than 18 years, insufficient contrast enhancement in imaging and contrast-enhanced imaging, thin vascular structure, and motion and contrast artifacts; the remaining 100 patients were included in this study. The age range of these patients was 3 months to 18 years (mean age 4.4 years).
In congenital heart diseases, attention to the coronary arteries on thoracic CT angiography examination in the presence of possible coronary anomalies may provide useful information.
本研究旨在评估因先天性心脏病接受胸部CT血管造影的患者的冠状动脉情况，确定先天性心脏病中冠状动脉异常的检出频率，并确定哪种类型的异常在何种疾病中更为常见。
在我们的研究中，使用128层多探测器计算机断层扫描机进行胸部CT血管造影。采集参数根据患者年龄设置为80 - 100 kVp，管电流时间积（mAs）由设备根据患者体重自动确定。检查期间，静脉注射非离子型对比剂，剂量为1 - 1.5 mL/kg。使用自动注射器以1.5 - 2 mL/s的速率注射对比剂。在轴位平面上，提取2.5 mm的层面，并以0.625 mm的层厚进行重建。
2022年10月至2024年5月期间，对在我院经超声心动图诊断为先天性心脏病并接受胸部CT血管造影的132例患者进行回顾性评估。在评估的患者中，32例因年龄小于3个月、大于18岁、成像中对比增强不足、对比增强成像、血管结构纤细以及运动和对比伪影等排除标准被排除；其余100例患者纳入本研究。这些患者的年龄范围为3个月至18岁（平均年龄4.4岁）。
在先天性心脏病中，在可能存在冠状动脉异常的情况下，胸部CT血管造影检查时关注冠状动脉可能会提供有用信息。
