title: Transcatheter closure of patent ductus arteriosus: experience with a new device.
abstract: Transcatheter closure is the preferred method of treatment of patent ductus arteriosus (PDA). Detachable coils are widely used to close small ducts, while the Amplatzer duct occluder (ADO) is generally employed for moderate or large ducts. Recently a new device, the Amplatzer duct occluder II (ADO II), a nitinol flexible mesh, with a symmetrical design to provide high conformability for treatment of all types of PDA, has received the European Community mark approval. We report on one of the first experience, four cases (1 male, 3 female, age ranging from six months to seven years old) with different type and size of PDA treated with the new device. The use of this new Amplatzer duct occluder in our experience has the advantage of ease and safety of placement, conformability, stability, low profile catheters, adaptability for long ducts as in type E.
