krazyaboutkatz-i'm so sorry about your mom's heart troubles.did her dad also have an enlarged heart?
I dated a guy many years ago that just had a heart transpant at 26 years old...from heredatery genes.His mom has had an enlarged heart...his mom's brother had a heart transplant from an enlarged heart and now his sister's 15 year old boy has an enlarged heart.
only him (The guy i dated)and his uncle needed the transplant.
I hear the 26 year old is in his early 40's married with kids and his uncle is still alive after 20 something years after his heart transplant.
They can do wonders(Some doctors with hearts).
I hope for the best and future good health for your mom.I also think you should get yours checked early,for early detection so you can live to be 110 years old.
Oh...the guy i dated was written up in all the local papers about his heart and the job well done by the doctors.His family has done remarkable.
