Closure of an Aortopulmonary Window Using the Amplatzer Duct Occluder II

Abstract

We report two cases of transcatheter-device closure of aortopulmonary windows, a residual defect occurring after previous surgical closure, and a native lesion. The postsurgical defect was closed with an Amplatzer Duct Occluder II (AGA Medical Corporation, MN). The native lesion was not suitable for an Amplatzer Duct Occluder II device; thus, it was closed using an Amplatzer Duct Occluder (AGA Medical Corporation, MN). The Amplatzer Duct Occluder II provides an additional device for aortopulmonary window closure, but anatomy and defect characteristics dictate the most appropriate device.

Transcatheter Closure of Late-Onset Residual Aortopulmonary Septal Defect Using a Muscular Ventricular Septal Occluder

“…In previous reported cases, some interventionists chose the aortic side to create tracts and deploy devices. 6) However, in this case, the fistula was directed inversely from the aortic side. A venous access was preferable for establishing the tract.…”

“…1) Experience with transcatheter closure for this type of defect is also limited. [1][2][3][4][5][6] We describe a case of successful transcatheter closure of a late-onset residual defect after repair of aortopulmonary septal defect using a muscular occluder device. This experience with device closure was unique because the shape of the lesion increased the diffi culty and the rare device was originally designed for closure of muscular ventricular septal defect (mVSD).…”

Surgical Repair of Complex Aortopulmonary Window: A Case Study

“…It is categorized into three types by Mori: (1) type I or proximal defect, which is located 1-1.5 cm away from the aortic valve, (2) type II or distal defect, which appears and disappears between the distal ascending aorta and the pulmonary artery, and (3) type III or the complete defect [8] . At present, the right pulmonary artery that originates from the aorta is classified as type IV defect [9,10] . In this case study, the patient suffers from an extremely rare deformity, i.e ., type I combined with type IV.…”

Transcatheter Treatment of Aortopulmonary Window with a Symmetrical Membranous Ventricular Septal Occluder

“…For example, Stamato et al [5 ]described the transcatheter closure of an APW in a 3-year-old child using a modified double umbrella occluder system. Furthermore, Naik et al [1 ]and Peer et al [4 ]used an Amplatzer ASD device to close a 6.0-mm APW and an Amplatzer duct occluder to close a 3.0-mm APW. In addition to these studies, Li et al [8] reported the successful treatment of a residual shunt after surgical repair of an APW with a muscular ventricular septal occluder.…”

“…However, recently several reports have shown that transcatheter closure may represent another option. For example, several APW cases were treated with Rashkind umbrella devices (Bard, New Providence, NJ, USA) and various Amplatzer Occluders (AGA Medical Corporation, Plymouth, MN, USA) [4,5]. Herein, we report closure of an APW using a symmetrical membranous ventricular septal occluder device (SVSDO, Beijing Starway Medical Technology, China), originally designed for closure of membranous VSD.…”
