First-in-man pulmonary artery stenting in children using the Bentley® BeGrow™ stent system for newborns and infants

•Repetitive stent redilations in children with CHD are frequently necessary to accommodate for somatic growth.•The Bentley BeGrow™ stent system offers a stent design allowing post-dilation steps up to Ø11.5mm to follow vessel growth.•Predetermined breaking points allow the stent struts to break in a controlled manner when exceeding a diameter of 11.5mm.•The BeGrow™ stent system offers new treatment options for transcatheter stent implantations in newborns and infants.•It can be effectively implanted. Longer follow-up will evaluate redilations and controlled stent strut breakage.
