Cardiac myxoma arising from the inferior vena cava.

This report documents what we believe to be the first reported case of a cardiac myxoma originating from inferior vena caval tissue. Myxomas account for 50 percent of cardiac tumors and present with either embolic, obstructive, or constitutional symptoms and signs. Diagnosis is facilitated by angiography and echocardiography and should be followed promptly by careful and complete removal of the mass and adjacent tissue with close follow-up by clinical and echocardiographic examinations.
