case_images: Two-dimensional echocardiography showed highly mobile, snake-like structures with a slightly higher echodensity as compared to myocardium, in the right and the left atria as well as the left ventricular apical septum (Figure 1).

case_images: An open excision of the cardiac masses was performed (Figure 2).
case_images: Histopathology of the surgical specimen revealed all three masses to be a cardiac metastasis from an unknown origin of a squamous cell carcinoma
