Atrial myxoma - Treatment

Treatment:

The tumor must be surgically removed. Some patients will also need their mitral valve replaced. This can be done during the same surgery.

Myxomas may come back if surgery did not remove all of the tumor cells.

Expectations (prognosis):

Although a myxoma is not cancer, complications are common. Untreated, a myxoma can lead to an embolism (tumor cells breaking off and traveling with the bloodstream), which can block blood flow or cause the myxoma to grow in another part of the body. Myxoma fragments can move to the brain, eye, or limbs.

If the tumor grows inside the heart, it can block blood flow through the mitral valve and cause symptoms of mitral stenosis. This may require emergency surgery to prevent sudden death.

Complications:

• Arrhythmias
• Pulmonary edema
• Peripheral emboli
• Spread (metastasis) of the tumor
• Blockage of the mitral heart valve

Calling your health care provider:

Tell your health care provider if there is any family history of myxomas or if you have symptoms of atrial myxoma.
