Intracardiac myxoma

Cardiac myxoma is the most common clinical primary cardiac tumor. It is generally considered to be benign, with some complex manifestations and malignant tendencies, but it is also considered to be a low-grade malignant true tumor. Myxomas can occur on the endocardial surface of all hearts, 95% in the atrium, about 75% in the left atrium, 20% in the right atrium, and 2.5% in the left and right ventricles. Myxoid tumors of the left atrium often occur near the ovary fossa. Clinically, the mitral valve mouth is often blocked by tumors, resulting in stenosis or incomplete closure of the mitral valve mouth. Myxoma can occur at any age, but it is most common in middle age. More common in women.
