Transcatheter closure of patent ductus arteriosus with buttoned device: first successful clinical application in a child.

Several devices are available for transcatheter closure of PDA. Most of the available devices either require complicated intracardiac maneuvering or need a large-sized sheath for implantation of the device. A recently described "buttoned" device developed by Sideris et al. that can be delivered across the ductus via a 7F sheath had undergone successful trials in animal models. Because of the ease of device implantation and the requirement for a smaller-sized sheath for delivery than that used with other devices, we have used this custom-made double-disc device in a 5-year-old child and have shown successful closure of the ductus by angiography and by color Doppler studies. Further clinical trials with this device seem warranted.
