Around or under?: "Water under the heart" does not make sense. Perhaps you are thinking of fluid in the sac that surrounds the heart, which is a pericardial effusion. That has many possible causes, including inflammation, thyroid disease, connective tissue diseases, just to name a few. If pericardial effusion is the diagnosis, you need to see a cardiologist to find the cause.
