Initially he consulted other surgeons, but this yielded conflicting advice. So Austin turned to 3D printing for help.

Using the facilities at the University of Louisville’s engineering school, Austin and his medical team produced a three dimensional model of little Ronald’s heart. Pediatric operations are difficult because the interior structures of a child’s organs are small and hard to see clearly. This model allowed the surgical team to come up with a precise plan to limit the amount of exploratory incisions, reduce operating time and prevent the need for follow-up operations.
