The characteristics of right heart intracardiac mass in hepatitis B virus infection patients are not clearly understood. Hence, a study was conducted to establish the ultrasonographic features and nature of such masses.

Su and colleagues conducted a retrospective review of imaging reports of hepatitis B virus infection patients between January 2014 and December 2018. Patients with a confirmed right heart intracardiac mass were included and their pathology reports and contrast-enhanced images were assessed. Several masses were compared to a general control group from a published study.

In all, 38 cases were included in the analysis. Varied masses presented with a range of echocardiographic manifestations. Overall, 36 cases had masses located in the right atrium, including five thrombus and 31 metastatic carcinoma - one metastatic non-Hodgkin lymphoma and 30 metastatic hepatic carcinoma cases (27 of these had inferior vena cava tumor thrombus). Two cases had masses in the right ventricle - one multiple myxoma and one tricuspid valve leaflet vegetation. In comparison with the general population, no primary malignant tumor was found in the current study and hepatic metastasis was the most common type of malignant tumor.

Hepatitis B virus infection patients have right heart intracardiac masses of diverse nature and ultrasonographic features. The incidence of malignant tumors was found to be similar to that seen in the general population. Hepatic metastasis, possibly extending via the inferior vena cava into the right atrium, was the most common type.
