Printing A Human Heart

We’re not to the point of printing working organs yet, (although we are getting closer), but 3D printing technology recently played a very cool part in the care of an infant who underwent surgery for a double outlet right ventricle.

From 3D Printing Industry.com:

The infant’s heart was riddled with defects before the surgery at the Hospital and his surgeon, Dr. Erle Austin, said that he had anticipated that the surgery would be tricky and thus sought a model that offered more detail than traditional 2D scans.

I found a video from courier-journal.com describing the collaboration between University of Louisville J.B. Speed School of Engineering and the physicians at the University of Louisville. Click on the image below to go to see it (you will be redirected to a new site).

From the video I learned that radiologists sent images of the infant’s heart, and those were translated into a program that the printer could handle. The heart was printed 50% larger than than life-size, with a flexible rubber-like substance, and in three segments so physicians could see “inside” the heart prior to starting the surgery! This allowed the docs to estimate how long the surgery would take, and foresee potential outcomes and complications.

3D surgical planning models, custom-printed for the patient. Personalized medicine, indeed!

    Ok, that’s bloody cool. I’ve been thinking about getting a 3D printer, now that some of them are really starting to get into the affordable range (not much more than the early inkjets).

    Hi there just wanted to give you a quick heads up. The words in your article seem to be running off the screen in Safari. I’m not sure if this is a format issue or something to do with browser compatibility but I figured I’d post to let you know. The design look great though! Hope you get the problem solved soon. Cheers

    I have been surfing online more than 3 hours today, yet I never found any interesting article like yours. It is pretty worth enough for me. Personally, if all webmasters and bloggers made good content as you did, the net will be much more useful than ever before.
