CTICasesLVAD Outflow Cannula Obstruction
Imaging findings
Filling defect within the bend relief of the LVAD outflow cannula, often with smooth margins.
Key takeaways
These defects are frequently proteinaceous debris or "gel" trapped between the inner and outer layers of the bend relief, not thrombus. Distinguishing this from actual thrombus prevents unnecessary anticoagulation changes.
