This report describes a case of left ventricular pseudoaneurysm examined by phonocardiography, two-dimensional echocardiography, Doppler color flow mapping, continuous wave and conventional pulsed Doppler echocardiography. The patient had early systolic and early diastolic murmurs. The pseudoaneurysm sac and the site of left ventricular rupture were identified by two-dimensional echocardiography. The flow between the left ventricle and the pseudoaneurysm were imaged by Doppler color flow mapping. Two jets from the left ventricle were directed toward the aneurysm during systole, and from the aneurysm toward the left ventricle in early diastole. Continuous wave Doppler and high pulse repetition frequency Doppler echocardiography demonstrated the maximum flow velocity in systole to be 3 m/sec and in early diastole, 1.7 m/sec. Those flow patterns between the left ventricle and the pseudoaneurysm could have been closely related to the murmur. Doppler echocardiography thus proved useful for detecting specific flow patterns related to a left ventricular pseudoaneurysm.
本报告描述了一例通过心音图、二维超声心动图、多普勒彩色血流图、连续波和传统脉冲多普勒超声心动图检查的左心室假性动脉瘤病例。患者有收缩早期和舒张早期杂音。二维超声心动图确定了假性动脉瘤囊和左心室破裂部位。多普勒彩色血流图显示了左心室与假性动脉瘤之间的血流情况。收缩期有两股来自左心室的血流射向动脉瘤，舒张早期则有血流从动脉瘤射向左心室。连续波多普勒和高脉冲重复频率多普勒超声心动图显示收缩期最大流速为3米/秒，舒张早期为1.7米/秒。左心室与假性动脉瘤之间的这些血流模式可能与杂音密切相关。因此，多普勒超声心动图被证明对检测与左心室假性动脉瘤相关的特定血流模式很有用。
