Abstract
Obstruction within the circuit of a left ventricular assist device (LVAD) is a challenging situation for clinicians to definitively diagnose and manage. Available diagnostic tools are limited in their ability to visualize large portions within the device and cannulas, often leading to uncertainty as to whether redo surgery is required or if there are feasible medical or percutaneous alternatives. Here, we report a case of LVAD outflow graft obstruction, which by computed tomographic angiography (CTA) appeared to be intramural thrombus, but by intravascular ultrasound (IVUS) was shown to be compression external to the graft.This publication has 4 references indexed in Scilit:
