Introduction/Background: Central venous catheters (CVC) are commonly utilized in cancer patients for prolonged systemic anti-cancer treatments but increased the risk of right atrial thrombosis (C THR ). Cardiac MRI (CMR) tissue characterization is commonly performed to identify C THR based on absence of vascularity.
Research Questions/Hypothesis: How do catheters affect thrombus formation?
Goals/Aims: To evaluate predictors of thrombus formation in cancer patients with CVC.
Methods/Approach: The population comprised of adult (≥18yo) systemic cancer pts with indwelling CVC who underwent contrast-enhanced CMR (0.2 mmol/kg gadolinium). C THR were defined using the reference of LGE-CMR via established criteria (absence of contrast enhancement). CVC depth was measured from CXR/CT. Clinical follow-up was obtained via chart review for embolic events.
Results/Data (descriptive and inferential statistics): 157 cancer pts with CVC (52±17 yo; 47% M; heme 29%
