Dear Carey,
It can be dificult to distinguish between the two. The onset and symptoms are nearly identical and the treatment is the same. The echo does not help to differentiate between the two. If you had a viral like illness before the onset of the heart failure that could indicate more of a viral
myocarditisMyocarditis picture. If a heart biopsy was done it could show changes that are consistent with viral myocarditis but in the absence of biopsy or viral titers I'm not sure the diagnosis can be made with certainity. It could have been PPCM or viral myocarditis. I would definately recommend seeing a specialist in heart failure before trying to conceive again. Best wishes.
