Successful transcatheter closure of patent arterial duct six years after balloon dilatation of coarctation of the aorta

A boy underwent total transcatheter occlusion of a patent arterial duct six years after successful balloon angioplasty of a native coarctation of the aorta. After successful implantation of a 12 mm device in the patent arterial duct there was no gradient across the descending aorta and five hours later there was no residual leak across the occluded patent arterial duct as judged by color Doppler.
