I have had pericarditis in 2008. my most recent echo showed trace mitral an tricuspid regurgitation and a bright pericardium. what can this mean?

It's ok: Regurge means that a valve leaks. The valves keep blood flowing in the proper direction. A mild leak shouldn't affect you. It needs to be followed periodically b/c sometimes the leak may worsen. A note of bright pericardium by itself doesn't mean a lot. This can be associated with disease of the pericardium but with the absence of other findings or symptoms its probably residual of pericarditis.

Things to watch: The trace tricuspid and mitral valve regurgitation may be nothing, but should be followed, or monitored by an echocardiogram, every year or every other year. The bright pericardium is likely the result of the pericarditis (which is inflammation of the sack the heart sits in) the worry is that this brightness becomes scar tissue, that could cause some squeezing of the heart, also followed by echo.
