German researchers have developed lab-grown heart muscle patches, which could significantly help patients with advanced heart failure. Derived from stem cells, these patches can be stitched onto damaged hearts, with initial human and primate trials showing promising results. A clinical trial involving 15 patients is currently underway to further evaluate the treatment's long-term effects. So far, one patient reported no adverse side effects after receiving the implant, indicating the patches may integrate safely and effectively into heart tissue.
It's tricky because the tissues are floppy, and you have to take care to make it stay in shape.
Her case showed that new muscle can be added to failing hearts without safety concerns, such as tumours and arrhythmia.
