Use of an Amplatzer Vascular Plug to occlude a tubular type of patent ductus arteriosus

Abstract

= Abstract = Patent ductus arteriosus (PDA) is a common congenital heart defect. All PDAs, regardless of size or degree of symptoms, require occlusion. Transcatheter PDA occlusion features fewer complications than trans-thoracic closure. It is also more cost-effective and has an excellent occlusion rate. Therefore, transcatheter PDA occlusion is accepted as the standard treatment option for PDA. However, tubular-type PDAs are difficult to close with ordinary detachable coils or the Amplatzer Duct Occluder; thus, these lesions remain a challenge for transcatheter closure. We attempted to occlude a tubular-type PDA by using an oversized Amplatzer Vascular Plug, which allowed intraluminal packing of the ductus. By using this treatment method, PDA occlusion was achieved safely with an excellent final outcome. We suggest that this approach may be a good option for transcatheter closure of a tubular-type PDA.

Transcatheter closure with a “single lobe” Amplatzer Vascular Plug of a tubular patent ductus arteriosus in a neonate with transposition of the great arteries and heart failure

“…Only one other case of transcatheter closure case with the Amplatzer vascular plug has been reported in a 3 year old with a small duct. 6 Although we were successful, the use of this device can only be recommended in very selected cases because of the risk of residual shunt and potential haemolysis.…”

Successful Transcatheter Closure of a Residual Patent Ductus Arteriosus with Complex Anatomy after Surgical Ligation Using an Amplatzer Ductal Occluder Guided by Live Three-Dimensional Transesophageal Echocardiography

“…PDAs which have a tubular shape are more likely to have an unfavorable outcome. 10 Identification and location of the residual duct with complex anatomy remains a challenge. In our case, surgical ligation of the PDA caused the residual duct to have a long, distorted tubular shape.…”
