განსაზღვრება
Myxoma is the commonest cardiac tumor and constitutes 50% of all benign cardiac tumors in adults, but only 15% of such tumors in children. About 75% of primary cardiac tumors are benign. Most myxomas are found in the left atrium (75%) and, in decreasing frequencies, in the right atrium, right ventricle, and left ventricle.
