What are myxomas?
A myxoma is a benign (non-cancerous) growth in the heart. Myxomas can be as small as a few millimetres or grow to a few centimetres. Most myxomas develop in the area of the heart called the atrium, which is the top left chamber of the heart.
Are myxomas malignant?
Myxoma is a non-cancerous (benign) tumor of the heart. In fact, it is the most common primary heart tumor.
What causes cardiac Myxomas?
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.
What is an intracardiac mass?
Intracardiac masses visualized by echocardiography are most commonly due to thrombi, vegetations, or myxomas; however, a host of other masses occur in the heart as a conse- quence of benign and malignant tumors.
Where are Myxomas found?
An atrial myxoma is a noncancerous tumor in the upper left or right side of the heart. It most often grows on the wall that separates the two sides of the heart. This wall is called the atrial septum.
What are benign smooth muscle tumors called?
A leiomyoma, also known as fibroids, is a benign smooth muscle tumor that very rarely becomes cancer (0.1%). They can occur in any organ, but the most common forms occur in the uterus, small bowel, and the esophagus.
How do they remove heart myxoma?
Typically, surgical resection of an atrial myxoma is performed via a median sternotomy with the patient on cardiopulmonary bypass. Recurrence of a myxoma after surgical excision is extremely rare, and most patients have an excellent prognosis after surgery.
How fast does a myxoma grow?
Pathology showed a myxoma that measured 15 x 3 cm implying a growth rate of 1.36 x 0.3 cm/month.
What is a cardiac tumor?
A heart tumor, or cardiac tumor, is a rare, abnormal growth that develops in the heart. Heart tumors can occur in any location, such as on the valves, within the heart muscle, inside a chamber, or around the heart.
What is oscillating intracardiac mass?
An ICM was defined as an oscillating mass found on a lead and confirmed in multiple views by TTE or TEE. The location of the ICM was determined by echocardiography. ICM morphology (diameter and number) was also examined using the data obtained from the echocardiogram.
What is the medical dictionary definition of myxomatosis?

What kind of tumour is an intramuscular myxoma?
Pathology. Intramuscular myxomas are benign soft-tissue tumours of mesenchymal origin that present as a deeply seated mass confined to skeletal muscle. It is classically described as hypocellular and hypovascular and is composed of cytologically bland stellate and bipolar fibroblasts separated by abundant extracellular myxoid matrix 2.
Which is an inherited syndrome with multiple myxomatous tumours?
One of the inherited syndromes that include myxomatous tumours is Carney complex, where there are multiple myxomatous tumours, skin hyperpigmentation due to adrenal hyperfunction, schwannomas, testicular tumours and pituitary adenoma with production of growth hormones. This syndrome is inherited autosomal dominantly.
What are the signs and symptoms of a myxoma?
Signs and symptoms are different depending on the location of the tumour. They may be unnoticed if they grow in the inner organs or muscles. If the myxoma is in a skeletal muscle, the only symptoms are a presence of a growing mass without any pain and possible hormone problems.
