A 72-year-old woman with inferior myocardial infarction presented with both a pseudoaneurysm and a ventricular septal rupture detected by two-dimensional and Doppler echocardiography. The pseudoaneurysm originated from the junctional area between the inferior portion of the ventricular septum and posterior left ventricular wall. The short-axis view of two-dimensional echocardiography revealed an abrupt discontinuity of the junctional area and an echo-free space behind the left ventricular cavity. The communication orifice was 5 mm wide. Color Doppler echocardiography showed a left-to-right shunt flow from the pseudoaneurysm to the right ventricle was visualized. Combined use of two-dimensional and color Doppler echocardiography was useful for detecting a pseudoaneurysm resulting in rupture of the ventricular septum.
一名72岁下壁心肌梗死女性患者，经二维及多普勒超声心动图检查发现既有假性动脉瘤又有室间隔破裂。假性动脉瘤起源于室间隔下部与左心室后壁的交界区。二维超声心动图短轴观显示交界区突然中断，左心室腔后方有无回声区。交通口宽5毫米。彩色多普勒超声心动图显示可见从假性动脉瘤到右心室的左向右分流。二维和彩色多普勒超声心动图联合使用有助于检测导致室间隔破裂的假性动脉瘤。
