Hey. Two days ago my grandmother had and Implantable Cardiovascular Defirbilator installed. After the surgery, the doctors put blood in her from a volunteer. She previosly had a pacemaker, she has about 20% heart left, glicomia, and diebetes. Over the period of a few hours her face is really swelled up. Is this normal? If not, what are the possibilites that caused this?
