Mildly Enlarged Left Artrial?

How serious is this condition? I have been looking around on the internet and it's hard to gauge. Some say it may be a sign of congestive heart failure, others say it may lead to an enlarged left ventricle, etc etc.

Does anyone here know if a mildly enlarged left atrial is anything to worry about? My doctor says no but you never know.. I don't like messing around with my heart!! uggh I am only 21 if that has any bearing on the condition.

I think your doctor is correct.  But, what made it become enlarged? Congenital?

If something is causing it to continue to enlarge that could be a problem.  

I have an enlarged left atrium due to a leaky mitral valve.  That has been repaired.  I suffer from Atrial Fibrillation, which is often associated with an enlarged left atrium.  Do you have any AFib symptoms?  If not, you condition is likely nothing to worry about, I believe.
