It was the moment he has been waiting for over almost a year.

The day Ari Schultz found out he was getting his new heart. The five-year-old has was diagnosed with critical aortic stenosis in the womb and has spent most of his life in and out of the hospital in Boston. This video of him finding out the life-changing news has gone viral and you can understand why. Little Ari received his new heart last week and if he survives the first year - he will be on medication for his whole life. His parents say they are so proud of his progress and that they are forever thankful for the donor and donor families sacrifice. They say they will think about them every day for the rest of our lives.   They are also encouraging people to donate their organs - without which, Ari wouldn't be alive today.
