A 33-year-old patient with nonischemic cardiomyopathy presented with cardiogenic shock requiring percutaneous left ventricular assist device placement despite inotropic support. Under transthoracic two-dimensional echocardiographic guidance, an Impella 2.5 L heart pump was placed. The inflow catheter was distal to the aortic valve, however patient remained in shock. Real time three-dimensional transthoracic echocardiography showed the inflow catheter imbedded into the papillary muscle causing inlet occlusion. By cropping 3D data set in multiple planes, a better spatial visualization of the inflow catheter and its distance from the aortic valve was easily obtained and the device was adjusted.
一名33岁的非缺血性心肌病患者出现心源性休克，尽管使用了血管活性药物支持，但仍需要放置经皮左心室辅助装置。在经胸二维超声心动图引导下，植入了一台Impella 2.5 L心脏泵。流入导管位于主动脉瓣远端，但患者仍处于休克状态。实时三维经胸超声心动图显示流入导管嵌入乳头肌导致入口阻塞。通过在多个平面裁剪三维数据集，可以轻松获得流入导管及其与主动脉瓣距离的更好空间可视化，并对装置进行了调整。
