About This File

Transposition of the great arteries is a serious but rare heart defect present at birth, in which the two main arteries leaving the heart are reversed (transposed). Transposition of the great arteries is usually detected either prenatally or within the first hours to weeks of life.


Transposition of the great arteries changes the way blood circulates through the body, leaving a shortage of oxygen in blood flowing from the heart to the rest of the body. Without an adequate supply of oxygen-rich blood, the body can't function properly and a child faces serious complications or death without treatment. Corrective surgery soon after birth is the usual treatment for transposition of the great arteries.



There are three STL files available for download segmented as seen in the video and images. These files have been zipped to save space and data transfer.

Great scan. I plan on printing it soon for my wife, who was born with this defect. The only things I had to do in preparation for the print was to clean up some artifacts (small parts floating in mid-air), and lay the print flat on the print bed. I might end up rethinking the last part after I see what the supports and base look like. Looking forward to it!


My one question is, what is the scale for the heart?  Are we looking at a 1:1 scale, or has it been enlarged for study?
