Persistent truncus arteriosus requiring truncal valve surgery is associated with poor prognosis.1 Valve replacement should be avoided for neonates or young infants; however, truncal valve repair (TrVR) sparing native leaflets has limitations because leaflet tissues are often dysplastic and very fragile. Glutaraldehyde-treated pericardium, which is commonly used in adult valve surgery, has unresolved problems in terms of calcification and toxicity, especially in children. We report a novel TrVR in which we used ethanol-treated pericardium.
