In brief: Fluid around heart
Heart muscle is covered by very thin layer of tissue called epicardium. Further surrounded by very thin partially distensible sac called pericardium. Space between epi- and peri- cardium always contains small amount of lubricating fluid.
Epi or pericardium can become inflammed or fluid can leak into this space. When fluid accumulates and becomes detectable it is an "effusion.".
