We present the apparently unique M-mode and two-dimensional echocardiographic features of a surgically confirmed pseudoaneurysm of the left ventricular outflow tract, which probably developed as a result of perforation of the mitral-aortic intervalvular fibrosa. Echocardiographic studies revealed an aneurysmal sac situated between the aortic root and the left atrium. The aneurysm expanded in systole and collapsed or emptied in diastole, suggesting direct communication with the left ventricle. Such an aneurysm must be differentiated from various pathologic findings of the aortic root. The location and characteristic motion during the cardiac cycle should alert the clinician to the correct diagnosis of such an aneurysm.
我们展示了经手术证实的左心室流出道假性动脉瘤明显独特的M型和二维超声心动图特征，该假性动脉瘤可能是由于二尖瓣 - 主动脉瓣间纤维穿孔所致。超声心动图研究显示，一个瘤样囊腔位于主动脉根部和左心房之间。该动脉瘤在收缩期扩张，在舒张期塌陷或排空，提示与左心室直接相通。这种动脉瘤必须与主动脉根部的各种病理表现相鉴别。心动周期中的位置和特征性运动应提醒临床医生对这种动脉瘤做出正确诊断。
