PURPOSE
Our goal was to evaluate the role of electron-beam CT (EBT) in the diagnosis of patients with coronary artery anomalies with a shunt.
METHOD
We performed EBT in seven patients with coronary artery anomalies with a shunt. Four cases were coronary artery fistula (CAF) and three were an anomalous origin of the left coronary artery from the pulmonary artery (ALCA from PA). Serial single volume mode scanning was performed at end-diastole to evaluate the anatomical course of the anomalous coronary arteries. Cine mode scanning was done in all but one to examine the ventricular wall motion and volumetrics.
RESULTS
EBT could detect the course and drainage sites of all CAFs and ALCAs from PA. Cine mode scanning revealed reduced wall motion in one case with CAF and two cases with ALCA from PA.
CONCLUSION
EBT serves a useful role in the assessment of coronary artery anomalies with a shunt.
目的
我们的目标是评估电子束CT（EBT）在诊断伴有分流的冠状动脉异常患者中的作用。
方法
我们对7例伴有分流的冠状动脉异常患者进行了EBT检查。其中4例为冠状动脉瘘（CAF），3例为左冠状动脉起源于肺动脉（ALCA from PA）。在舒张末期进行连续单容积模式扫描，以评估异常冠状动脉的解剖走行。除1例患者外，其余均进行电影模式扫描，以检查心室壁运动和容积。
结果
EBT能够检测出所有CAF和ALCA from PA的走行及引流部位。电影模式扫描显示，1例CAF患者和2例ALCA from PA患者的心室壁运动减弱。
结论
EBT在评估伴有分流的冠状动脉异常中发挥着有用的作用。
