目的评价多普勒超声心动图诊断完全性大动脉转位(D-TGA)冠状动脉解剖类型的准确性,提高超声心动图的首次检出率。方法经外科手术证实为D-TGA的118例患者为研究对象,回顾性分析其超声心动图表现。结果118例患者中,正常冠状动脉104例(88.1%),异常冠状动脉14例(11.9%)。回旋支发自右冠状动脉、单支右冠状动脉、右冠状窦内两支冠状动脉比较多见。超声诊断正确者6例,占42.8%;误诊4例,占28.6%;不能显示4例,占28.6%。心血管造影明确冠状动脉畸形后,两个医生进行超声检查,正确率可提高至71.4%。结论超声心动图可以比较准确地诊断D-TGA患者的冠状动脉异常,主动脉位于右侧及合并室间隔缺损者易合并冠状动脉畸形。
Objective To evaluate the accuracy of Doppler echocardiography in the diagnosis of coronary artery anatomy of complete aortic transposition (D-TGA) and to improve the first detection rate of echocardiography. Methods One hundred and eighteen patients with D-TGA confirmed by surgery were enrolled in this study. The echocardiographic findings were retrospectively analyzed. Results Of the 118 patients, 104 (88.1%) had normal coronary arteries and 14 (11.9%) had abnormal coronary arteries. Circulatory branches from the right coronary artery, single right coronary artery, right coronary coronary artery more common. Ultrasound diagnosis in 6 cases, accounting for 42.8%; 4 cases misdiagnosed, accounting for 28.6%; can not show 4 cases, accounting for 28.6%. Cardiovascular angiography Correct coronary arteries, the two doctors ultrasound examination, the correct rate can be increased to 71.4%. Conclusion Echocardiography can diagnose coronary artery abnormalities more accurately in D-TGA patients. The aorta is located on the right side and the ventricular septal defect is complicated by coronary artery deformity.
