What is a myxoma?

A myxoma is a rare, noncancerous tumor that forms in the heart. It can be found in either atrium (the upper chambers of the heart) or ventricles (the lower chambers of the heart). Myxomas are usually smooth and round, and they range in size from a few millimeters to several centimeters.

Myxomas are benign, which means they do not spread to other parts of the body. However, they can cause serious problems by blocking the flow of blood through the heart. This can lead to heart failure, stroke, or other complications.

The exact cause of myxomas is unknown, but they are thought to be caused by a genetic mutation. Myxomas are more common in women than in men, and they are most often diagnosed between the ages of 30 and 60.

Symptoms of a myxoma can vary depending on the size and location of the tumor. Some people may experience no symptoms at all, while others may have symptoms such as:

* Shortness of breath

* Chest pain

* Fatigue

* Lightheadedness or dizziness

* Fainting

* Heart palpitations

* Cough

* Wheezing

* Difficulty swallowing

If you experience any of these symptoms, it is important to see your doctor right away.

Myxomas are diagnosed based on a physical exam, imaging tests such as echocardiogram or MRI, and a biopsy.

Treatment for a myxoma usually involves surgical removal of the tumor. In some cases, medication may also be used to treat symptoms.

The outlook for people with myxomas is generally good if the tumor is diagnosed and treated early.
