Abstract

A 2-year-old child was implanted with an Berlin Heart EXCOR Ventricular Assist Device (Berlin Heart, Berlin, Germany) as a bridge to heart transplantation for idiopathic dilated cardiomyopathy. At postoperative day 296, a significant reduction of membrane movement was observed. The device was explanted and tested on a hydronumerical circulation simulator. Findings suggested that the integrity of the multilayered membrane had been compromised. This was confirmed by a computed tomography scan of the device. The computed tomography evidenced a detachment of the 3-layered membrane, with a thinner, convex layer on the side of the air chamber and an opposite convexity of the remaining membranes. These showed an additional air space within the layers.

摘要

一名2岁儿童因特发性扩张型心肌病植入了柏林心脏EXCOR心室辅助装置（德国柏林心脏公司）作为心脏移植的过渡。术后第296天，观察到膜运动明显减少。该装置被取出并在水力数值循环模拟器上进行测试。结果表明，多层膜的完整性受到了损害。该装置的计算机断层扫描证实了这一点。计算机断层扫描显示三层膜分离，气室一侧有一层较薄的凸层，其余膜则有相反的凸度。这些显示层内有额外的空气间隙。
