Novel procedure for treatment of aortic obstruction caused by amplatzer occluder of patent ductus arteriosus.

An 18-month-old boy with patent ductus arteriosus and pulmonary hypertension is reported, in whom deployment of the Amplatzer ductal occluder caused significant aortic obstruction, requiring the inflation of an intraortic balloon against the aortic retention disk of the device as a new procedure to treat such an obstruction. This case emphasizes the need for careful hemodynamic and angiographic assessment of the position of the Amplatzer ductal occluder before and after detaching the device from its delivery system, with particular emphasis on the aortic retention ring and the possibility of interventional management of this complication.
