Heart Surgery and Treatment has come a long way.
New beating heart patch allows surgeons to restore function to damaged heart tissue by implanting the patch over the dead muscle and so it can remain active for a long time, providing more strength for contractions and a smooth path for the heart's electrical signals to travel through. These patches also secrete enzymes and growth factors that could help recovery of damaged tissue that hasn't yet died.
The cells for the beating heart patch are grown from human pluripotent stem cells
The researchers place stem cells at specific ratios into a jelly-like substance where they self-organize and grow into functioning tissue to become fibroblasts, cardiomyocytes, endothelial and smooth muscle cells to form blood vessels
Where is the research being conducted?
Biomedical engineers at Duke University (North Carolina, USA) have created a fully functioning artificial human heart muscle large enough to patch over damage typically seen in patients who have suffered a heart attack. The advance takes a major step toward the end goal of repairing dead heart muscle in human patients. If you want to contact Duke for a cardiology consultation, surgery or to learn more about this research, we can help you schedule a consultation.
For decades, people all over the world have faced this dilemma and solved their problem with medical travel.
Unlike some human organs, the heart cannot regenerate itself after a heart attack. The dead muscle is often replaced by scar tissue that can no longer transmit electrical signals or contract, both of which are necessary for smooth and forceful heartbeats. But there's more to this than simply post heart attack treatment. When the heart muscle no longer functions properly, the end result is a disease called heart failure that affects over 12 million patients worldwide. New therapies, such as the one being developed at Duke are needed to prevent heart failure and its lethal complications.
Current clinical trials test the method of injecting stem cells derived from bone marrow, blood or the heart itself directly into the affected site in an attempt to replenish some of the damaged muscle. Although some positive effects are being realized from these treatments, their mechanisms are not fully understood. Fewer than one percent of the injected cells survive and remain in the heart, and even fewer become cardiac muscle cells. The scientists and researchers are hoping the large patches can be implanted over the dead muscle and remain active for a long time. This enables a "backup" to provide enhanced strength for contractions and a smooth path for the heart's electrical signals. These patches would also secrete enzymes and growth factors that could help recovery of damaged tissue that hasn't yet died. If the patch is not as strong as the original heart tissue a difference in strength could cause deadly arrhythmia.
