ABSTRACT
Introduction Since balloon atrioseptostomy was introduced by Rashkind et al.1 in the early 1960s, the number of transcatheter interventions in newborns and small infants has continuously increased. Today, a broad variety of interventional procedures can be performed safely in very small patients on a routine basis. ese interventional procedures include preoperative palliations such as the Rashkind procedure, alternative treatment options to surgical procedures such as balloon dilatation in pulmonary valve stenosis and a wide spectrum of postoperative interventions to optimize surgical results.
