Epidemiology
Malignant and benign primary cardiac tumours are extremely rare, with a reported incidence in autopsy series of 0.02%.[2] Myxoma is the most common cardiac tumour, and constitutes 50% of all benign cardiac tumours in adults.[3] It is not as common in children and accounts for only 15% of such tumours. About 75% of primary cardiac tumours are benign. Most myxomas are found in the left atrium (75%) and, in decreasing frequencies, in the right atrium, right ventricle, and left ventricle. The incidence of myxomas peaks at 40 to 60 years of age. They are more common in women, with a female-to-male ratio of 3:1.[4]
