A laboratory at Tel Aviv University showed off an incredible technological test by using a 3D printer to create a small artificial human heart, which may be a breakthrough in coronary medicine.

Video of the manufacture shows the heart being printed at the laboratory of Professor Tal Dvir on April 15. The procedure is hoped to use heart tissue from patients to print heart 'replacements' before being transplanted back into the donor.

The organ is the first heart to be printed with cells and complete set of blood vessels, with animal transplant trials to begin next year according to news reports.
