Get to know atrial myxoma, a benign tumor in the lining of the heart & bull; hello healthy

Definition

What is atrial myxoma?

Atrial myxoma is a benign (non-cancerous) tumor that starts in the lining of the heart (endocardium). As many as 90 percent of atrial myxomas occur in the atrium, usually on the left atrium and on the wall (septum) that separates the two sides of the heart.

How common is atrial myxoma?

Based on research, atrial myxoma is usually first seen at an average age of 56 years. Twice more cases in women than men. You can treat this condition by reducing risk factors. Talk to your doctor for more information.

Signs & symptoms

What are the signs and symptoms of atrial myxoma?

Atrial myxoma signs and symptoms are:

Difficulty breathing or shortness of breath
Headache or dizziness
Chest pain
Swelling of the legs
Fainting
Fever
Drastic weight loss without cause
Palpitations
Muscle ache

A new stroke can be caused by a buildup of blood that has moved from the tumor to the brain. Blood in the lungs can cause difficulty breathing. In severe cases, symptoms also include unexplained blue (bruised) skin, coughing, and curved nails (clubbing), and general discomfort that is felt throughout the body.

Cause

What causes atrial myxoma?

Risk factors

What increases my risk for atrial myxoma?

Certain factors that can increase the risk of atrial myxoma are

Gender. women have a higher risk of developing atrial myxoma than men.
Age. The average age of patients with atrial myxoma was 56 years or more.

Medicines & Medicines

What are my treatment options for atrial myxoma?

The most common treatment for atrial myxoma is surgical removal of the tumor.

When the diagnosis is made, surgery should not be postponed because sudden death can occur while waiting for surgery. Complications from surgery include pain, infection, arrhythmias (rhythmic disorders of the heart), and sudden death.

Surgery can improve life expectancy very well, with life expectancy as high as 95 percent after 3 years. However, up to 5 percent of cases are sporadic and up to 20 percent of cases of hereditary myxoma can recur within the first 6 years after surgery.

What are the usual tests for atrial myxomas?

Your doctor will use your medical history and physical exam for diagnosis. The best test to detect atrial myxoma is echocardiography. Echocardiography uses sound waves to create images of the heart and blood flow in it.
