Aim:
To describe the initial New Zealand experience of transcatheter patent ductus arteriosus closure in adults and children.
Methods:
Twenty-three children beyond infancy and four adults with isolated patent ductus arteriosus were selected for transcatheter umbrella closure. Rashkind umbrellas were placed across the patent ductus arteriosus through a percutaneously inserted long venous sheath using the Mullins technique.
Results:
In 25 of the 27 patients a Rashkind umbrella was placed accurately. In two patients the umbrella could not be placed accurately: in one the procedure was abandoned uneventfully and in one the umbrella embolised to the right pulmonary artery necessitating surgical removal of the device and patent ductus arteriosus closure. There were no other significant complications. A second umbrella insertion is planned in two children for a significant residual leak at 1-year follow up.
Conclusions:
Transcatheter patent ductus arteriosus closure is a low risk and usually effective alternative to surgical closure for the majority of patients beyond infancy.
