The new Amplatzer duct occluder II: when is its use advantageous?

Abstract

In our experience, duct closure with the Amplatzer duct occluder II is a safe and effective method. The advantages of using it are the smaller sheath sizes and softer shape.

Percutaneous closure of patent ductus arteriosus in children using amplatzer duct occluder II: Relationship between PDA type and risk of device protrusion into the descending aorta

“…Hemolysis could have occurred but may have been subclinical and requiring no blood transfusion. Our data on residual shunts and complication rate are similar to previously published literature . According to previously published data , the rate of procedure related complications is lower when device closure by ADOII is carried out in patients weighing >10 kg.…”

“…Percutaneous closure of PDA has become a gold standard treatment technique with multiple devices available on the market. The main challenge with this technique is to avoid protrusion of the aortic retention disc into the descending aorta especially in non‐conical types of PDAs that lack a sufficient ampulla.ADO II was introduced to overcome the inconveniences of closing PDAs with non‐conical configuration, with large diameter, and in small infants . The ADO II has very‐low‐profile discs that offer both more stability and higher conformability minimizing the risk of device‐related obstruction by adapting the device retention discs at different angles of PDA insertion into the aorta and the pulmonary artery.…”

“…Several studies have reported safety and efficacy of the ADOII in occluding almost all Krichenko angiographic types of arterial ducts . However, few studies define which out of the Krichenko PDA types are associated with higher risk of device protrusion into the descending aorta.…”

“…Device protrusion into the left pulmonary artery or the descending aorta is a well known possible complication of the procedure. Several studies have reported safety and efficacy of the new device . However, few studies define which out of the five Krichenko PDA types is associated with higher risk of device protrusion into the descending aorta.…”

Cost-effectiveness analysis of different devices used for the closure of small-to-medium-sized patent ductus arteriosus in pediatric patients

“…[29] ADO II device protrusion into the left pulmonary artery or the descending aorta is a possible complication of the procedure, although several studies have described the safety and efficacy of the device. [29303132333435]…”
