Researchers at tel aviv university said Wednesday they have created the world’s first 3d printing prototypes artificial heart — a heart made of cells, blood vessels, ventricles and Chambers — from a patient’s own tissue.But the resulting 3d printing prototypes heart, which can contract, has not yet pumped blood and needs to grow.
The cherry-sized heart was unveiled at a press conference in tel aviv, central Israel, in a “medical breakthrough” that could one day lead to printed hearts that can be transplanted.
The heart’s big break is complete: there are as many cells, blood vessels, ventricles and Chambers as there are Chambers.
Tel aviv university professor tal dwyer, who led the research, said researchers had previously been able to create a “simple” heart without blood vessels using a 3d-printed prototype.
Human tissue raw materials:
It can solve the problem of donor shortage and rejection,Because the 3d printing prototypes printed artificial heart tissue and cells from the patients themselves, it is expected to significantly reduce recipient rejection after transplantation.
Using the patient’s own tissue as “raw material,” dewell said, the patient would no longer have to wait or take drugs to prevent rejection.Instead, the technology will print out the organs a patient needs and adjust them accordingly.
On the other hand, the study may have benefits for people with heart failure.Cardiovascular disease is the leading cause of death worldwide, according to the world health organization.Organ transplantation is now the only option for seriously ill patients.But because of the limited number of donors, many patients die while waiting.Now, 3D printing prototype technology can open a new path in medicine, paving the way for future organ transplantation.
Dewell said he hopes that within the next decade, the world’s best hospitals will have 3d printers for human organs that can be routinely printed for transplant.He also says hospitals may start with organs simpler than the heart.
