Common locations include upper back, shoulders, and abdomen. [4] It is possible to have several lipomas. [3] The cause is generally unclear. [1] Risk factors include family history, obesity, and lack of exercise. [1] [3] Diagnosis is typically based on a physical exam. [1] Occasionally medical imaging or tissue biopsy is used to confirm the ...
A subset of the primary tumors of the heart are tumors that are found on the valves of the heart. Tumors that affect the valves of the heart are found in an equal distribution among the four heart valves. [2] The vast majority of these are papillary fibroelastomas. Primary tumors of the valves of the heart are more likely to occur in males.

The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).
The calf muscles are your “second heart,” squeezing veins in the lower legs to help return deoxygenated blood from the feet back up towards the chest, the Cleveland Clinic notes.

Lack of exercise is another common cause of water retention in the legs. Exercise helps the leg veins work against gravity to return blood to the heart. If blood travels too slowly and starts to pool in the leg veins, the pressure can force too much fluid out of the leg capillaries into the tissue spaces.
Hypertrophic cardiomyopathy (HCM, or HOCM when obstructive) is a condition in which muscle tissues of the heart become thickened without an obvious cause. [8] The parts of the heart most commonly affected are the interventricular septum and the ventricles. [10]
