Abstract

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.

Keywords: Computed tomography; heart failure; mechanical circulatory support; thrombosis.
