An atrial myxoma is a noncancerous tumor in the upper left or right side of the heart. It grows on the wall that separates the two sides of the heart. This wall is called the atrial septum.
A myxoma is a primary heart (cardiac) tumor. This means that the tumor started within the heart. Most heart tumors start somewhere else.
Primary cardiac tumors are rare. Myxomas are the most common type of these rare tumors. About 75% of myxomas occur in the left atrium of the heart, usually beginning in the wall that divides the two upper chambers of the heart. The rest are in the right atrium.
