Three years after the repair of a true left ventricular aneurysm, a 62-year-old man was admitted to our department for spontaneous angina pectoris and heart failure. The two-dimensional echocardiogram revealed a uniformly dilated left ventricle with a large apical aneurysm, in which a thin, continuous, band-like echogenic structure, extending from the interventricular septum to the antero-lateral wall could be visualized. That structure was initially interpreted as a left ventricular false tendon. Color Doppler flow imaging, however, showed a continuous, phasic flow crossing the band-like structure. Thus, the diagnosis of a huge apical pseudoaneurysm was made and subsequently confirmed by angiographic findings. In conclusion, left ventricular pseudoaneurysms may present themselves with unusual morphologic features. In patients with equivocal two-dimensional echocardiographic findings, color Doppler flow imaging is helpful in clarifying morphologic ambiguities and in identifying unsuspected flow abnormalities.
在真正的左心室动脉瘤修复三年后，一名62岁男性因自发性心绞痛和心力衰竭入住我科。二维超声心动图显示左心室均匀扩张，伴有巨大的心尖部动脉瘤，在其中可看到一个薄的、连续的、带状的回声结构，从室间隔延伸至前侧壁。该结构最初被解释为左心室假腱索。然而，彩色多普勒血流成像显示有连续的、呈阶段性的血流穿过该带状结构。因此，诊断为巨大的心尖部假性动脉瘤，随后血管造影结果证实了这一诊断。总之，左心室假性动脉瘤可能呈现出不寻常的形态特征。在二维超声心动图结果不明确的患者中，彩色多普勒血流成像有助于澄清形态学上的模糊之处，并识别未被怀疑的血流异常。
