Stem cell patch repairs hearts without surgery

Mayo Clinic develops a stem cell patch to repair damaged hearts without open-heart surgery, showing promise in preclinical tests.

Why it matters

  • Offers a less invasive option for heart failure treatment.
  • Could revolutionize treatment for severe heart failure patients.

By the numbers

  • Preclinical testing showed improved heart function and healing.
  • Human clinical trials could start in five years.

The big picture

  • The patch uses lab-grown heart tissue from stem cells.
  • Delivered through a tiny incision, avoiding open-heart surgery.

What they're saying

  • Testing was likely done in animals (mice or rats).
  • Hopes it will translate to human applications.

Caveats

  • Preclinical testing only; not yet tested in humans.

What’s next

  • Larger-scale preclinical testing planned.
  • Human clinical trials estimated to start in five years.
