About This File
Double aortic arch is a relatively rare congenital cardiovascular malformation. Double aortic arch is an anomaly of the aortic arch in which two aortic arches form a complete vascular ring that can compress the trachea and/or esophagus.
Embryologically, the aorta's right sided 4th arch failed to regress which resulted in this double aortic arch and vascular ring. Depending on how tight the ring is, symptoms in infancy are related to respiratory compression, compared to a later presentation in childhood or adulthood of swallowing difficulty.
Please see the related STL file for 3D printing double aortic arch blood pool model.
There are 3 separate files so the heart can be printed in slices. A fourth STL files is for 3D printing the whole heart model. The three part model has holes for magnets, which can be used to connect and separate the pieces. A US quarter is shown for scale in the images below.
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 Congenital Heart Defects library. We thank Dr. Bramlet and all others who are working to help children with congenital heart problems lead normal and happy lives.
