Could the enlargement in the heart be due to viral infection?
Patient: My sister in law has just been told she seems to have an enlarged heart.  She has had a virus recently which affected her throat and chest.  They seem to be saying that it could be due to the virus and she is to have hospital tests done soon to investigate it.  Could a virus cause this - or is it something she may have had for years?  How serious could it be? Doctor: What's her age? Viral myocarditis can cause cardiomegaly.. Cardiomyopathy can be due to virus also...but not so common...need to know excatly what she has and examine to give ur answer. If u can send me her 2D echo report and tell more history , probably o can help. I hope this is helpful reply to u.
