  • Revolutionary 3D-bioprinted patch that can help heal scarred heart tissue after a heart attack

A 3D printed patch has been made that could immensely help such patients who have suffered from a heart attack in the future.

A group of biomedical engineers have managed to manufacture a highly advanced 3D printed patch. It has the capability to fix scar tissue formed in patients after a heart attack. This is very good news for cardiac patients. Now they can have their heart tissue healed after suffering from a heart attack.

A patent for this 3D printed patch has been filed as well. According to the AHA, heart disease is the #1 killer of Americans. Each year it takes at least 360,000 lives. During the course of a heart attack, a person loses the blood supply reaching his or her heart muscle.

This causes the cells to start dying rapidly. Functionality in the cardiac muscle is lost and the body cannot replace the lost tissue which remains in the form of scars. This in turn leaves the patient prone to further attacks and vulnerable to further complications to say the least.

In the study, a laser beam was employed to bioprint a 3D patch which also had stem cells as a part of its makeup. These stem cells had been obtained from adult human heart cells in the form of a matrix.

This matrix grew in a petri dish which had nutrients supplied to it. The grown cells were also able to expand and contract in synch with their natural rhythm as heart tissue normally do.

The cell patch was first tested in a rodent. It began to function in as little time as a month’s duration. Furthermore, this patch was so natural that is soon melded in with the rodent’s heart tissue and could not be differentiated. There was thus no need for any further surgeries.

This is a revolutionary step in the treatment of heart disease in America. Once it is brought to the level of human beings, the age of the heart attack may be over for all we know.

This may take place within the next couple of years. The biotechnology is still a nascent one. The integration of the heart tissue into the damaged heart of the rodent was in an absolutely perfect manner.

This shows that this procedure holds great promise for the future. The researchers were really surprised to see their efforts bear fruit in the lab.

The research effort is published today in the American Heart Association journal Circulation Research.
