Long‐term clinical experience with amplatzer ductal occluder II for closure of the persistent arterial duct in children

Abstract

The ADO II is effective for occlusion of PDA with variable anatomy from either arterial or venous approaches with a low profile delivery system. Stable occluder position is highly dependent on accurate device sizing, good quality imaging to visualize device configuration after deployment and operator experience.

Outcome after transcatheter occlusion of patent ductus arteriosus in infants less than 6 kg: A national study from United Kingdom and Ireland

“…The efficacy and safety profiles of percutaneous patent ductus arteriosus (PDA) closure are well‐documented in older infants, children, and adults . Evidence in smaller infants, however, is limited to a few small studies with variable outcomes .…”

Transthoracic Echocardiography‐Guided Percutaneous Patent Ductus Arteriosus Occlusion: A New Strategy for Interventional Treatment

“…Complete occlusion on echocardiography was found in 84.6% of cases immediately after the procedure and 100% at the time of discharge. The most frequent complications associated with percutaneous closure of PDA include device embolization, protrusion of the retention disk of the device into the aorta producing aortic obstruction, or obstruction of a branch pulmonary artery by the device . In the present study, no patients were found to have these complications during follow‐up.…”

“…However, to avoid completely the use of fluoroscopy, the technique of device placement itself must be as safe as possible under echocardiographic guidance. Studies of percutaneous PDA occlusion with ADO II occluder under fluoroscopy guidance indicated excellent results with occlusion rate of 96–100% and a low incidence of complications . In the present study, percutaneous PDA occlusion under TTE guidance was successfully performed in 62 patients (62/63, 98%).…”

“…Percutaneous patent ductus arteriosus (PDA) occlusion has become the preferred therapeutic option since its introduction more than three decades ago . Although the occluder and device delivery system have been modified during these years, fluoroscopy and angiography have been used as the guidance modality ever since.…”

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]…”
