title: Transcatheter occlusion of patent ductus arteriosus.
abstract: This article reviews the current status of transcatheter technology, which has been applied to close the patent ductus arteriosus (PDA). Pioneering work in this field was performed by Porstmann in the 1960s and Rashkind in the 1970s. Devices which have been implanted in the PDA have basic designs as plugs, umbrellas, or coils. The experience reported with each type of device is detailed. Issues and controversies are examined. It appears that coils should be the preferred method for closing smaller PDAs (3-mm diameter or smaller), and Rashkind or similar devices, if available, should be reserved for larger PDAs (> 3-mm diameter). Surgery is necessary for neonatal and for rare large PDAs. Transcatheter technology is still evolving and may become more effective and cheaper.
