摘　　要：目的探讨超声心动图诊断法洛四联症合并左前降支异常起源于右冠状动脉的可能性。方法分析5例法洛四联症合并左前降支异常起源于右冠状动脉患儿的超声心动图二维图像表现，并与心血管造影、手术结果对比分析，总结其诊断要点。结果除法洛四联症的超声表现外，超声特异表现有：在高位心底动脉短轴观直接看到左前降支起源于右冠状动脉，并横过右室流出道；右冠状动脉粗大；左冠状动脉近端无分支。超声诊断均与心血管造影、手术结果符合。结论超声心动图诊断法洛四联症合并左前降支异常起源于右冠状动脉具有较高的准确性，在法洛四联症的诊断中，应提高对本畸形的认识。Objective To study the value of echoeardiography for diagnosis and to discuss the features of the anterior descending artery originating from the right coronary artery in tetralogy of Fallot （TOF）. Methods The echocardiographic characteristics of the anterior descending artery originating from the right coronary artery in TOF in five cases were compared with the results of cardiac catheterization and operation. The diagnostic features of echocardiography were summarized. Results Besides the five cases had the echocardiographic characteristics of TOF, other echocardiographic characteristics were： anterior descending artery originating from the right coronary artery and crossing the right ventricular outflow tract were visualized in suprasternal short-axis view. Right coronary artery became larger than normal. There was no branch could be see at beginning of the main left coronary artery. The echocardiographic characteristics of the anterior descending artery originating from the right coronary artery in TOF cases were correspondent to the results of cardiac catheterization and operation. Conclusions There is high accuracy of echocardiography to diagnosis the anterior descending artery originating from the right coronary artery in TOF. Coronary artery abnormalities should be alerted in TOF.
