Norton's Children's Hospital in Louisville is celebrating a big milestone as doctors there perform their 100th pediatric heart transplant.

Details in today's medical news.

Norton Children's Heart Institute said doctors performed the transplant on a nine year old patient Monday.

He had been on the transplant waiting list for almost a year.

Norton Children's Heart Institute began performing heart transplants on pediatric patients almost 40 years ago and is the only pediatric program in the state capable of doing the procedure.

We have seen a steady growth in the number of patients that are receiving transplant and the number of patients who are followed by the heart failure service.

So it's always exciting to reach this milestone.

Obviously, we are taking care of some sick patients and we we see them going through all the stages of the treatment and getting better.

And it's definitely very gratifying.

I bet it is.

And 2020.

Norton Children's Hospital opened the Jennifer Lawrence Cardiac intensive care unit.

The famous actress and Louisville native donated $2 million to the hospital to build the unit.

The 17 bed unit features private rooms dedicated to children recovering from heart procedures and other conditions requiring intensive care.
