Hi Lisa
I also have an enlarged heart, but I am not sure if it is the same issue as what you have going on, sounds something like what els posted--I have been looking for more information too...
They found mine on Echo and my results say left atrial enlargement and concentric left ventricular hypertrophy. Still not fully sure what alot of this means. I have been told that it is mild and probably a result of my high blood pressure. I take several medications and have been told not to worry to much about
it, and am currently getting another opinion on all of my health issues, so we will see-I am 29 and they are unsure why I have such uncontrolled hypertension despite repeated attempts with meds...
I hope they find the cause of yours and let me know if you get anymore answers than I did--I would be curious to learn more on this topic. Els thanks for the links!!! Please, if anyone else knows anymore let me know. Thanks..
Edited to add: I keep meaning to ask the same question you had--can it eventually go back to it's normal size once the underlying cause is treated? I'll have to write it down--I always get to the doctor and forget!
