| Abstract: | BACKGROUND: Cardiac magnetic resonance (C-MR) differentiates cardiac metastasis (C-MET) and cardiac thrombus (C-THR) based on tissue characteristics stemming from vascularity on late gadolinium enhancement (LGE). Perfusion CMR can assess magnitude of vascularity; utility for cardiac masses (C-MASS) is unknown. OBJECTIVES: This study sought to determine if perfusion CMR provides diagnostic and prognostic utility for C-MASS beyond binary differentiation of C-MET and C-THR. METHODS: The population comprised adult cancer patients with C-MASS on C-MR; C-MET and C-THR were defined using LGECMR: C-MASS+ patients were matched to C-MASS- control subjects for cancer type/stage. First -pass perfusion CMR was interpreted visually and semiquantitatively for C-MASS vascularity, including contrast enhancement ratio (CER) (plateau vs baseline) and contrast uptake rate (CUR) (slope). Follow-up was performed for all -cause mortality. RESULTS: A total of 462 cancer patients were studied, including patients with (C-MET = 173, C-THR = 69) and without C-MASS on LGE-C-MR. On perfusion C-MR, C-ER and CUR were higher within CMET vs CTHR (P < 0.001); CUR yielded better performance (AUC: 0.89-0.93) than CER (AUC: 0.66-0.72) (both P < 0.001) to differentiate LGE-CMR-evidenced C-MET and C-THR, although both CUR (P = 0.10) and CER (P = 0.01) typically misclassified C-MET with minimal enhancement. During follow-up, mortality among C-MET patients was high but variable; 47% of patients were alive 1 year post-CMR. Patients with semiquantitative perfusion CMR-evidenced CMET had higher mortality than control subjects (HR: 1.42 [95% CI: 1.06-1.90]; P = 0.02), paralleling visual perfusion CMR (HR: 1.47 [95% CI: 1.12-1.94]; P = 0.006) and LGE-CMR (HR: 1.52 [95% CI: 1.16-2.00]; P = 0.003). Among patients with CMET on LGE-CMR, mortality was highest among patients (P = 0.002) with lesions in the bottom perfusion (CER) tertile, corresponding to low vascularity. Among C-MET and cancermatched control subjects, mortality was equivalent (P = NS) among patients with lesions in the upper CER tertile (corresponding to higher lesion vascularity). Conversely, patients with C-MET in the middle (P = 0.03) and lowest (lowest vascularity) (P = 0.001) CER tertiles had increased mortality. CONCLUSIONS: Perfusion CMR yields prognostic utility that complements LGE-CMR: Among cancer patients with LGE-CMR defined C-MET, mortality increases in proportion to magnitude of lesion hypoperfusion.
