Thanks for writing to us.
i understand your concern but i am sorry to say that it is not clear from question that what kind of problem your friend has? inflammation of left atrium is not a known medical entity. it must be actually something else. i would like you to inquire from your doctor and revert back to us with exact medical diagnosis
, so that i can tell you more about this . i would also like to know what surgery was done on this girl. What symptoms/problems she had prior to surgery?
if you can come up with these details i would be glad to discuss more.
