Now scientists believe they have made a breakthrough by creating implantable patches composed of beating heart muscle that can help the organ contract.

Prof Ingo Kutschka, the co-author of the work from University Medical Center Göttingen in Germany, said: “We now have, for the first time, a laboratory grown biological transplant available, which has the potential to stabilise and strengthen the heart muscle.”

The patches are made from cells taken from blood and “reprogrammed” to act as stem cells, which can develop into any cell type in the body.
