CTICasesProtectDuo Right Ventricular Assist Device
Imaging findings
CT demonstrates a dual-lumen single cannula assist catheter (ProtectDuo) inserted via the internal jugular vein. The double-lumen portion lies in the right atrium (inflow) and the single-lumen tip extends through the RVOT into the main pulmonary artery (outflow).
Key takeaways
The ProtectDuo is a specialized percutaneous right ventricular assist device (RVAD) used for acute right heart failure (e.g., post-LVAD placement). Radiologists should recognize its characteristic trajectory from the internal jugular vein to the main pulmonary artery, bypassing the right ventricle.
