Script

This can’t really be real. Gemma Starks wants to show you her heart and she can, because of new 3-D technology.

Doctor:“From this three-dimensional blueprint, we sent it over to our 3-D printer where your home printer has paper and ink; this uses powder that’s bound together by super glue and ink. This is what those tiny little hearts will look like.”

Even before surgery, Gemma’s doctors have a better picture of what is going on from more than one angle. Dr. Stephen: “Having the models beforehand allows us to analyze and really set a pathway for the surgery.”Dr. John:“It’s personalized medicine on steroids, because you have a 3-D model of the child's actual size heart with all the subtle abnormalities that are wrong with the heart.”

It also means less time in the operating room and fewer complications. Born with half a heart, Gemma’s mother finds comfort in knowing she has one less thing to worry about.

Stephanie: “Knowing that he was able to look at this, before he went in to operate changes everything for me, it instills a lot more confidence in the process, he’s not going to open her up and find a major surprise. He knows what he’s looking at, he knows what he’s going to do.”

It is what the creator behind the heart models was going for.

Dr. David: “When you tell a mother that her child has total anomalism, that’s why total anomalous pulmonary venous return that doesn’t mean so much, but when you can take a model like this, and say we'll see that green vessel there that shouldn’t be there.”

No longer, just in the hands of surgeons for the first time, Stephanie Starks gets to take home her daughter’s very own heart model.

Stephanie:“This is your heart.”

Stephanie:“Holding this tells me that there’s hope and confidence for these kids.”

Dr. David:“There’s no limits to this technology ,we’re getting more detailed information, that detailed information will allow for us to make better precise decisions, better therapies, but more importantly, maybe prevention of congenital heart disease al together .”

Stephanie: “It inspires me, I overcome, you know, any every fear, looking at this heart and knowing that you can do anything.”

Pre-reading Questions

1.3-D painting is known as additive manufacturing which builds an object from the bottom up by piling razor-thin layers of materials on top of each other until a three-dimensional shape emerges.

2.(Open ended) Yes, it may solve the problem of donated organ shortage, and the technology has the potential to replace testing on animals, which can be slow, expensive and not always accurate. No, it still has a long way to go since scientists must determine not only what types of cells to use, but how to expand them in the lab and how to keep them alive and viable throughout the engineering process.
