Heartbeat: Melody Valve

This is Jacob's fourth major heart procedure and his dad says the past surgeries have left his boy scarred, but only physcially.

"Yeah, he's a happy kid. I mean, he goes to school, enjoys life. I mean, you get to know him, it's real hard to forget the kid.

But thanks to an amazing piece of technology, his most recent procedure will leave nothing but a small dot on Jacob's neck.

It's called the transcatheter pulmonary valve, or melody valve for short.

The $30,000 valve is inserted into a small tube, and according to Jacob's doctors, will go through his neck and into his heart.

"It's a valve that comes from a cow. From the jugular vein of a cow. As you know, they graze, so they put their heads down. Also, this valve helps the blood not go into their heads."

"Imagine yourself getting wires through a wall in your house. So, you need to put a wire and you need to put a hole in the very bottom part and top part, and not destroy the whole entire wall. This is the same way."

Once the valve is in place, the surgeon inflates the balloon and then deflates it before he pulls the wire back out, thus repairing the defect, for now.

"It's a platform that has changed, dramatically, the way we look at things. Because instead of having to do this, in an absolutely invasive manner, we're going less and less invasive. But with the same safeguards that we've had up until now."
