Sorry, but there's not enough information to work with. The best thing for you to do is ask your cardiologist about this. Since six years have passed, time's a-wasting.
Short question, short answer... Inflamation itself does not cause scarring. However being inflamed/enlarged can lead to tissue rubbing or stretching which can cause scarring.
Nobody wants another one!!!!
