Medical progress makes people happy: Heart patch with 3D technology

American scientists have created a medical revolution in restoring scarred heart tissue, sequelae of a heart attack, with a 3D patch. This is considered an extremely important step in the treatment of damaged heart tissue for patients.

Statistics from the American Heart Association show that heart attack is the leading cause of killing more than 360,000 Americans each year. When a person has a heart attack, blood cannot be transported to the heart muscle, causing them to die and form scars as the human body cannot replace new heart muscle cells. These scars will become the culprit affecting the function of the heart and make a person with heart failure in the future.

According to a study published recently in the Circulation Research Journal of the American Heart Association, scientists from many US universities, led by the University of Minnesota, used 3D laser printing technology to print a patch after modeling the heart cell structure with a 3-dimensional scanner and then grow it in a laboratory. The patch is the stem cell taken from adult heart cells.

Results in experimental mice showed that the patch works very effectively, significantly improving the function of the heart. It becomes part of the heart and adapts to the body without surgery.

Professor Brenda Ogle at the University of Minnesota said that the study will be conducted more widely than animals even in humans over the next few years.

Currently, scientists are ready to create larger patches to test on pig hearts. Pig heart is about the same size as human heart.
