Technologies are increasingly entering the field of medicine. But when it comes to heart surgery, they can play a decisive role. See how in the United States a heart made with a 3D printer helps surgeons.

Perfection comes with practice.  Researchers at the University of Washington are creating 3D heart rate models for patients in need of surgical intervention. Thus doctors are given the opportunity to exercise on the specific organ with all its specifics.

The patient's heart is scanned and a computer-based 3D model is created. The file with it is loaded in the 3D printer. When printed, the model has - so to say - matrix remnants - that must be cleaned before being surrendered to the surgeons.

Laparoscopic operations have long been preferred all over the world for lack of incisions. And such 3D models give an excellent idea of the heart, on which they work and facilitate their work, ultimately benefiting patients.
