Echocardiography has proven a useful and sensitive means to determine noninvasively the cardiac dimensions. This report describes the echocardiographic detection of progressive dilatation of the aortic root over an 18-month period, which led to death in a 33-year-old man with Marfan's syndrome; however, at no time was the aortic dilatation evident on chest x-ray films. This patient illustrates the sensitivity of the echocardiogram in detecting and assessing the severity of disease of the aortic root not readily assessed by other noninvasive techniques and the value of serial measurements of aortic dimensions in patients with proven or suspected dilatation of the aortic root.
超声心动图已被证明是一种有用且敏感的手段，可用于无创测定心脏大小。本报告描述了一名33岁马方综合征男性患者在18个月期间超声心动图检测到的主动脉根部进行性扩张，最终导致死亡；然而，胸部X光片在任何时候都未显示出主动脉扩张。该患者说明了超声心动图在检测和评估主动脉根部疾病严重程度方面的敏感性，而其他无创技术不易做到这一点，同时也说明了对已证实或疑似主动脉根部扩张患者进行主动脉尺寸系列测量的价值。
