This three-part 3D printed heart is from a CT scan of a 4-year-old infant with Tetrology of Fallot, a congentital heart defect and the most common cause of blue baby syndrome. It is characterized by stenosis (narrowing) of the pulmonary artery, an abnormal defect of the ventricular septum, an "overriding" aorta, and hypertrophy of the right ventricle. This patient has had a corrective surgery called Blalock-Taussig shunt.
The three STL files have been zipped and available for download. Alternatively, one STL file representing the whole model is also available for download. The three part model has holes for magnets, which can be used to connect and separate the pieces. The magnets can be found on a site which specializes in rare earth magnets.
The model is provided for distribution on Embodi3D with the permission of the author, pediatric cardiologist Dr. Matthew Bramlet, MD, and is part of the Heart Library. We thank Dr. Bramlet and all others who are working to help children with congenital heart problems lead normal and happy lives.
