Anomalous origin of the coronary arteries, though uncommon, is of great clinical concern. It can be the cause of sudden cardiac death and abnormal cardiac hemodynamics. Advances in electrocardiographically (ECG)-gated multi-detector CT have increased diagnostic accuracy in detecting anomalous origin of coronary arteries and their interarterial and intramural courses. Recent advances in multi-detector CT image processing software have allowed the creation of virtual endoluminal views of the aortic root and improved assessment of the intramural course (the length and relationship to the intercoronary commissure) of the coronary artery, which is of considerable surgical importance. We review our experience with virtual endoluminal imaging in our first 19 cases of interarterial coronary artery anomalies (17 cases of interarterial with intramural segment and 2 cases of purely interarterial course) diagnosed preoperatively and proven surgically.
冠状动脉异常起源虽然不常见，但具有重要的临床意义。它可能是导致心源性猝死和异常心脏血流动力学的原因。心电图门控多排 CT 的进步提高了检测冠状动脉及其动脉内和壁内走行异常起源的诊断准确性。多排 CT 图像处理软件的最新进展允许创建主动脉根部的虚拟腔内视图，并改善对冠状动脉壁内走行（长度和与冠状动脉交叉之间的关系）的评估，这在手术中具有相当重要的意义。我们回顾了我们在 19 例动脉内冠状动脉异常（17 例伴壁内段和 2 例单纯动脉内走行）患者中的虚拟腔内成像经验，这些患者术前诊断并经手术证实。
