Pauline, as you are finding out, getting a transplant is not as easy as going to the hospital and laying on the O.R. table. they put you through all kinds of tests to know you are a good candidate. they also want to know that once given a transplant you will take good care of it.
the ventricle thing may be just the way you are but the team sure doesn't want anything to happen during the surgery.
be sure to keep us informed.
