FDA clears first expandable heart valve for growing children

The U.S. Food and Drug Administration has granted approval for the Autus Size-Adjustable Valve, a pediatric pulmonary valve that can be expanded after implantation. Developed by Edwards, the valve starts at a 13-millimeter diameter for toddlers and can be enlarged to 22 mm via a balloon catheter, matching adult-size valves and reducing the need for repeated surgeries. Congenital heart disease impacts about 400,000 children each year in the United States, with valve abnormalities accounting for roughly 30 % of those cases.

Traditional artificial valves require surgical replacement as a child grows, but the Autus uses polymeric material for its flaps, which resists hardening and breakdown better than animal-derived tissue. CDC data indicate that pulmonary valve stenosis and atresia affect around 4,200 newborns annually. A study published in one outlet Library of Medicine reports that one-year follow-up shows the Autus maintains function longer than comparable devices.
