The FDA approved the first heart valve designed to expand after implantation for children with congenital pulmonary valve disease.
The valve does not grow on its own; a balloon catheter can widen it later as a child grows.
It starts at approximately 13 millimeters in diameter and can later expand to as much as 22 millimeters.
The approval covers pediatric patients with congenital pulmonary valve disease, including stenosis or atresia that restricts blood flow to the lungs.
Among the first 60 patients in a 62-patient study, blood-flow performance was acceptable at six months.
Three patients had valve-frame fractures, and two had reduced leaflet movement; those events caused no symptoms in affected patients.
The FDA says the valve may reduce repeat open-heart surgeries, but long-term benefit and durability remain under study.
