Using magnetic cameras, researchers at Linköping University have examined blood flow in an artificial heart in real time. The results make it possible to design the heart in a way to reduce the risk of blood clots and red blood cells breakdown, a common problem in today’s artificial hearts. The study, published in Scientific Reports, was done in collaboration with the company Scandinavian Real Heart AB, which is developing an artificial heart.

Most of the patients whose heart does not work at all are currently connected to a machine that takes care of their blood circulation for them. It is a large device, and the patient is confined to their hospital bed. For those patients, an artificial heart could be an option while waiting for a donor heart.
