Parasternal long axis view of the transthoracic echocardiogram of the patient
performed 8 months prior showing a normal left atrium and ventricle without
any mass.

Cardiac etiology was not pursued initially as the patient had a cardiac evaluation by her cardiologist and had a normal echocardiogram (except for findings of a patent foramen ovale) 4 months prior to onset of symptoms (Figure 1).
CT angiogram of the chest demonstrated a large intracardiac mass.

Previous chest CT scan was reviewed and a repeat CT chest not only showed a large intracardial mass measuring at 6.3 cm x 6 cm x 3 cm centered at the mitral valve but also present in the left atrium, with persistent left hilar lymph node, diffuse groundglass opacities in the lung parenchyma and pulmonary edema (Figure 2).
Transesophageal echocardiogram of the same patient showed a large echodense
mass, the myxoma in the left atrium (LA).

Preoperative planning with a transesophageal echocardiogram (Figure 3) revealed a large echo-dense mass in the left atrium bouncing into the mitral valve into the upper part of the left ventricle.
