A patient with heart failure due to dilated ischemic cardiomyopathy presented in cardiogenic shock for institution of veno-arterial extracorporeal membrane oxygenation as a bridge to cardiac transplantation. To provide adequate venous drainage and simultaneous decompression of the left atrium (indirect left ventricular venting), a single venous cannula was placed across the interatrial septum so that the distal orifice and side ports were located within the left atrium and the proximal set of side ports were positioned at the cavoatrial junction. Three-dimensional transesophageal echocardiography demonstrated utility in guiding cannula placement and appropriate positioning within the left atrium.
一位患有扩张型缺血性心肌病心力衰竭的患者出现心源性休克,需要进行静脉-动脉体外膜肺氧合以作为心脏移植的桥梁。为了提供足够的静脉引流并同时对左心房进行减压(间接左心室通风),将一根单腔静脉插管穿过房间隔,使远端开口和侧端口位于左心房内,而近端侧端口位于腔静脉交界处。三维经食管超声心动图在指导导管放置和在左心房内的适当定位方面具有实用性。
