The Heart Program at Miami Children’s Hospital (MCH) is believed to be the first in the region to use three-dimensional printing technology to create a model of a patient’s heart to support pre-surgical planning for a child who was born with a complex heart anomaly. Four-year old Adanelie Gonzalez was born with total anomalous pulmonary venous connection (TAPVC), a complex congenital heart defect in the veins leading from the lungs to the heart. Although she has already undergone two complicated open-heart operations and multiple cardiac catheterizations, the surgeries had only proven a temporary fix and her health was quickly deteriorating.
The team turned to the MCH Cardiac 3D modeling team, consisting of Dr. Robert Hannan, Cardiac Surgeon, Dr. Juan Carlos Muniz, Director of Cardiac MRI and Chelsea Balli, Biomedical Engineer for The Heart Program, to print a 3D model to better visualize the patient's complex anamoty and to explore potential options for repair.
“I think about heart repairs in three dimensions, imagining what I will do with my hands during each step of the operation,” said Dr. Redmond Burke, Director of Cardiovascular Surgery of The Heart Program at MCH. “I thought that holding and manipulating a flexible 3D replica of this child’s heart might allow me to plan an operation that hadn’t been done before, configuring the necessary patches to create the exact shapes and dimensions to match her deformed pulmonary veins.”

Magnetic resonance imaging (MRI) and Computed Tomography (CT) image files were collected and rendered by MCH’s cardiologists and the biomedical engineer who reformatted the image files to be read by a 3D printer. The files were then printed by AdvancedRP, an Atlanta-based distributor of Statasys 3D printers.
Dr. Burke was able to intricately study the heart model, manipulating the vessels and exploring possible repairs as he would employ in the operating room.
Dr. Nancy Dobrolet, Pediatric Cardiologist at The Heart Program at MCH says,
“3D printing adds another element in caring for extremely complex conditions where surgical intervention is not typically thought possible. In Adanelie’s case, the 3D model provided us with way to create a surgical option for her survival.”
