What is a trivial pericardial effusion.?
You have a sac which surrounds your heart called the pericardium, it normally contains a small amount of fluid. This sac prevents friction from occuring on the heart while it is beating (so it doesn’t rub against other organs). If you have a pericardial effusion, it means that there is fluid buildup in the sac moreso than normal. A trivial effusion is too small to consider tapping and draining it with a needle, and your body will likely reabsorb the excess.
