- The problem
- Synthetic vascular grafts are widely used in congenital heart reconstruction, but complications can limit care. Tissue-engineered grafts offered growth potential, yet some narrowed over time.
- What advanced
- Researchers created a graft by placing a child’s own cells on a biodegradable tube so a blood vessel could grow as the tube dissolved. The CHF-supported proposal was designed to test whether losartan could prevent narrowing in an animal model.
- What it could mean
- If narrowing can be safely prevented, a living graft with growth potential could become an improved option for children undergoing congenital heart surgery.
