Little sister pacemaker machine

Hello everyone, this is my baby sister dulce she’s 7 years old. She was born with half a heart (Hypo left heart syndrome) she has gone through 4 surgeries one when she was just 3 days old and another a year later and the other the year after that.Now,this is her 4th she had in June 26,2019. In this surgery she was going to get a pacemaker place inside her and the surgery went very well. She will need a heart transplant in the future. Now we were informed that she will need pacemaker machine that will be checking the statuses inside of her but sadly the medical card didn’t cover it all. We need help and every little bit counts. Please and thank you!
