Diagnostic Considerations

Regardless of etiology, patients with untreated intracardiac masses are at risk for embolic complications, lethal arrhythmias, and symptoms of heart failure.

An inaccurate diagnosis (eg, thrombus) may subject patients to risky medical or surgical treatments (or a delay in surgical management).

In the absence of a tissue diagnosis, a mass presumed benign can represent a primary or metastatic malignancy.

Other conditions to consider in the differential diagnosis of cardiac masses include the following:

  • Atrial thrombus

  • Endocarditis

  • Intracardiac thrombus

  • Lung cancer

  • Lymphoma
