Cardiac Myxoma: A Rare Case Series of 3 Patients and a Literature Review.

Myxoma is the most common tumor in the heart. A typical myxoma is relatively straightforward to diagnose. However, certain cardiac myxomas have rare features. We report three extremely rare cases of cardiac myxoma. One case involved a myxoma that originated from the annulus of the tricuspid after valvuloplasty, one case involved myxomas associated with left atrial thrombus and severe mitral stenosis, and the third case involved myxoma combined with severe calcification. All three cases were diagnosed by echocardiography and pathology. We also review clinical presentations and diagnostic characteristics of cardiac myxomas.
