Can a myxoma be malignant?
Myxomas developing in three to four heart chambers are extremely rare and usually considered malignant cardiac tumors, especially when tumors located in other organs were detected (6–8).
What is a myxoma tumor?
Myxomas are tumors of connective tissue. They can occur almost anywhere in the body, including the heart. Treatment for a myxoma in the heart depends on many things. These include where the tumor is and if it is blocking blood flow. If the tumor is in the left atrium, surgery might be done to remove it.
Is cardiac myxoma curable?
Myxomas are curable with surgical removal. A myxoma is a benign tumor in the heart most commonly found in the left atrium. About 75% of myxomas are in the left atrium, usually beginning in the wall that divides the lower chambers of the heart (ventricles) and growing into the atrium.
Does myxoma require open heart surgery?
An atrial myxoma needs to be removed surgically as soon as possible to avoid irreversible damage to the heart, the brain or other distant organs that can be affected by the tumor. Atrial Myxoma affects women three times more often than men, and they are commonly diagnosed at a fairly young age.
How do you treat myxoma?
The only treatment of a myxoma is surgical excision. This needs to be performed by a highly skilled cardiac surgeon because incomplete removal can result in recurrence of the tumor. Once a patient is diagnosed with a myxoma, surgical excision is usually recommended to prevent complications.
What causes a cardiac myxoma?
Although there is not a well-defined underlying cause for myxomas, it is suspected to be the result of a combination of environmental and genetic risk factors. Cardiac myxomas can cause valvular obstruction, leading to episodes of fainting, pulmonary edema, symptoms of right heart failure, or embolisms.
Is myxoma benign or malignant?
Myxomas are rare benign tumors. They occur at various locations such as heart, bones, skin subcutaneous and aponeurotic tissues, urogenital tract and skeletal muscles.
What are the symptoms of myxoma?
Symptoms of a myxoma may include:
- Breathing difficulty when lying flat or on one side or the other.
- Breathing difficulty when asleep.
- Chest pain or tightness.
- Sensation of feeling your heart beat (palpitations)
- Shortness of breath with activity.
- Symptoms due to embolism of tumor material.
Is a myxoma serious?
Untreated, a myxoma can lead to an embolism (tumor cells or a clot that breaks off and travels in the bloodstream). This can lead to a blockage of blood flow. Pieces of the tumor can move to the brain, eye, or limbs. If the tumor grows inside the heart, it can block blood flow, causing symptoms of obstruction.
How fast does a myxoma grow?
The calculated growth rate showed an average growth rate of 0.49 cm/month. These reports suggest that the growth rate of myxomas may be faster than is usually thought.
How long can you live with a myxoma?
Long-term prognosis was excellent with an actuarial survival rate of 0.74. Specific immunologic alterations were found in 71.4% of the patients. The actuarial freedom from reoperation of the myxoma was 0.96. The rate of reoperations was low with 2.0% after 24 years.
Can a myxoma be removed?
Surgery is the only treatment for myxomas and should be arranged as soon as possible. During the surgery, your surgeon will make an incision down the centre of the breastbone, or via a small incision on the chest wall, to access the heart and remove the myxoma.
What is Myxoma of the heart?
Myxoma is a non-cancerous (benign) tumor of the heart. In fact, it is the most common primary heart tumor. A primary heart tumor is one that originates within the heart as opposed to another organ or tissue. Approximately 75% of myxomas are located within the left atrium.
What are the most common types of benign heart tumors?
The most common types of benign heart tumors are: Myxoma – most common primary cardiac tumor. Account for approximately 50% of primary cardiac tumors. Papillary fibroelastoma – most common cardiac tumor to affect the cardiac valves. Mean age at diagnosis is 60 years old.
What is a cardiac tumor?
A cardiac tumor is an abnormal growth of tissue in the heart, and may be classified as either cancerous (malignant) or non-cancerous (benign). Cardiac tumors are further classified as either primary (originating within the heart itself) or secondary (spread from a primary tumor in a different part of the body).
What happens if a myxoma is not removed?
This needs to be performed by a highly skilled cardiac surgeon because incomplete removal can result in recurrence of the tumor. Once a patient is diagnosed with a myxoma, surgical excision is usually recommended to prevent complications.
