Outflow graft obstruction is a potentially catastrophic complication of left ventricular assist devices that may occur secondary to different mechanisms. Two cases of Heartmate 3 outflow graft obstruction associated with two different pathophysiological mechanisms are presented. The first one was a 70-year-old man who developed outflow graft obstruction secondary to kinking. The second case was a 72-year-old man who presented with signs and symptoms of heart failure due to outflow graft extrinsic obstruction. Both cases were diagnosed with 3D-CT scan and successfully surgically treated.
流出道移植物梗阻是左心室辅助装置的一种潜在灾难性并发症，可能继发于不同机制。本文介绍了两例与两种不同病理生理机制相关的Heartmate 3流出道移植物梗阻病例。第一例是一名70岁男性，因扭结继发流出道移植物梗阻。第二例是一名72岁男性，因流出道移植物外部梗阻出现心力衰竭的症状和体征。两例均通过三维CT扫描确诊，并成功接受了手术治疗。
