Transcatheter closure of a patent arterial duct in a patient on veno-arterial extracorporeal membrane oxygenation.

The presence of a patent arterial duct may complicate the course of the patient on veno-arterial extracorporeal membrane oxygenation (ECMO). While surgical ligation has been traditionally used as a definitive treatment for this problem, transcatheter closure may have advantages. This is the first report of transcatheter occlusion of a patent arterial duct in an infant on ECMO support.
