What is Myxoma?

In this blog, we’ll be providing an overview of a rare non-cancerous growth we treat at Baylor Scott & White Greater Dallas Orthopaedics called Myxoma. Myxomas are the most frequent benign cardiac tumor in adults, accounting for 25% of cardiac tumors and more than 50% of benign cardiac tumors.

Myxomas can appear in other places, but most often develop in the top-left chamber of the heart, known as the atrium, and can grow between several millimeters and a few centimeters in size. They are made of connective tissues, which typically support other tissues throughout the body.


Myxomas are non-cancerous, as they are unable to invade other tissues. They often appear sporadically and without any underlying cause. 

What are the Causes of Myxoma?

While an exact cause is not known, both environmental and genetic factors can contribute to the occurrence of Myxomas. Approximately 1 in 10 cases of Myxoma are known to be genetic.


Who is Most Affected by Myxoma?

Myxomas are rare but occur mostly in women, whose symptoms may appear at a young age, as well as adults above the age of 40. Those with a familial history of Myxomas are more at risk.


What are the Symptoms of Myxoma?

Many Myxomas are entirely asymptomatic, but some people may experience difficulty breathing while lying down, coughing, fainting, or fatigue. Those with a Myxoma may also experience flu or stroke-like symptoms. 


How is Myxoma Treated?

While Myxomas are benign, they can be dangerous if left untreated. They may break off and travel in the bloodstream, causing complications in other parts of the body. The only way to treat a Myxoma is to surgically remove it. 

We hope this overview of Myxoma was insightful and enlightening. The team at Baylor Scott & White Greater Dallas Orthopaedics places a high value on informing our audience and improving the medical literacy of all we impact. 

As always, the content of a blog post is no substitute for a legitimate medical diagnosis. If you are concerned that you or a loved one may be suffering from Myxoma, prioritize an appointment with a qualified medical professional at your earliest availability.
