Six patients with aortic root dissection proved by angiography, surgery or autopsy, and six patients with aortic root dilatation were studied by echocardiography. Echocardiography was diagnostic in five or six patients with dissection and suggestive in the sixth, disclosing anterior and posterior dissection in three, anterior dissection in one and posterior dissection in one. The recording of a double echo in the aorta was the diagnostic feature. Angiography was diagnostic in four of the six patients, yielded a false negative result in one and was not performed in one. Six patients with dilatation had an enlarged aortic root by echocardiography. Left ventricular size, stroke volume, ejection fraction, aortic regurgitant flow and velocity of circumferential fiber shortening were calculated in 11 patients. Echocardiography was extremely helpful in the diagnosis, management and follow-up in patients with aortic dissection or dilatation.
6例经血管造影、手术或尸检证实为主动脉根部夹层的患者以及6例主动脉根部扩张患者接受了超声心动图检查。超声心动图对5或6例夹层患者具有诊断价值，对第6例具有提示意义，其中3例显示主动脉前后壁夹层，1例为前壁夹层，1例为后壁夹层。主动脉内双回声记录是诊断特征。血管造影对6例患者中的4例具有诊断价值，1例出现假阴性结果，1例未进行血管造影。6例扩张患者经超声心动图检查显示主动脉根部增大。对11例患者计算了左心室大小、每搏输出量、射血分数、主动脉反流流量和圆周纤维缩短速度。超声心动图对主动脉夹层或扩张患者的诊断、治疗和随访极为有用。
