What is the cause of cardiac lipoma?

summary

Cardiac lipoma is a benign tumor with intact adventitia and contains typical mature adipocytes. Lipoma can be located in all parts of the heart and pericardium. Intramyocardial lipomas are usually small and well encapsulated, occasionally on mitral or tricuspid valves. What is the cause of cardiac lipoma? Next, I'd like to share my views with you.

What is the cause of cardiac lipoma?

The tumor tissue of cardiac lipoma is composed of mature adipose tissue, which usually originates from the fat of epicardium or pericardium. It is surrounded by fibers and a little myocardial tissue, and contains the surrounding connective tissue.

The size of the tumor is different, and the effect on the heart is also different. Generally, the tumor is small, and patients seldom have symptoms; The tumor is large and oppresses the heart, resulting in corresponding symptoms. Intramyocardial lipomas are usually small and well encapsulated, occasionally growing on mitral or tricuspid valves, and microscopically composed of mature adipocytes.

The clinical manifestations are not characteristic. When the tumor is large and the cardiac function is damaged to varying degrees, it is often found by chance during the follow-up or routine physical examination. CT and MRI can achieve the purpose of diagnosis. However, MRI examination is more authoritative because it can not only show the size, location, tissue characteristics and blood flow type of the lesion,

matters needing attention

There is no preventive method for cardiac lipoma. Any population may suffer from disease. After the disease occurs, most patients have no symptoms, and a few patients will have precordial pain, angina pectoris, etc. patients should immediately go to the hospital for examination and treatment after the diagnosis of the disease.
