First-in-human, off-label use of BeGraft® stenting of non-conduit, large right ventricular outflow tract for transcatheter valve landing zone preparation

Abstract

Transcatheter implantation of pulmonary valve has emerged as a reliable approach in congenital heart patients presenting with chronic right ventricular volume or pressure overload after primary repair. Initial experience was limited by relatively narrow range of working diameter of transcatheter valves. Nowadays, improved technology allows extending this option to patient with large right ventricular outflow tract or conduit. A stable landing zone is of paramount importance before considering valve implantation. We present two cases of right ventricular outflow tract pre-stenting using the BeGraft® stent, which may become an interesting add to our tool kit in the preparation of valve landing zone.
