Using a phased-array, wide angle sector-scanner, 2-dimensional echocardiograms were obtained in 3 patients with persistent truncus arteriosus. Type I was found in 2 patients and type II in 1 patient. In the patient with type II truncal valve stenosis was also present. Using a combination of short-axis views at the cardiac base, within 30 degrees superior transducer angulation and parasternal long-axis views, the truncus arteriosus and the pattern of pulmonary arteries were demonstrated in each case.
使用相控阵广角扇形扫描仪，对3例永存动脉干患者进行了二维超声心动图检查。发现2例为I型，1例为II型。II型患者还存在动脉干瓣膜狭窄。通过心脏基部短轴视图、换能器向上成角30度以内的视图以及胸骨旁长轴视图相结合，在每例患者中均显示了动脉干和肺动脉的形态。
