Transcatheter Closure of Patent Ductus Arteriosus Using the Amplatzer Duct Occluder.

The Amplatzer duct occluder (ADO) (AGA Medical Corp., Golden Valley, MN) is designed to meet criteria for an optimal transcatheter technique for closure of a patent ductus arteriosus. It was developed as an alternative to surgical closure and other interventional techniques. It is not technically complex, allows controlled deployment, is retrievable and repositionable, and has a low risk of embolization. The ADO also has very high complete closure rate at 1-month follow-up comparable to surgical ligation and division.
