Ventricular septal defect closure in a small children with the Amplatzer Duct Occluder II

Abstract

Transcatheter technique for muscular ventricular septal defect closure remains challenging, particularly in small patients. We report the successful use of the low profile Amplatzer Duct Occluder II for multiple ventricular septal defect closure in an infant with D-transposition of the great arteries, status postpulmonary artery banding. The multiple apical ventricular septal defects were successfully closed with two Amplatzer Duct Occluder II and one Amplatzer Muscular Ventricular Septal Defect Occluder during two interventional catheterizations. The patient subsequently underwent successful surgical repair. V C 2011 Wiley-Liss, Inc.

Treatment of congenital non‐ductal shunt lesions with the amplatzer duct occluder II

“…Hence, device closure is difficult or impossible in infants and small children and in rare congenital anomalies with abnormal anatomy. Recently, the Amplatzer duct occluder II (ADO II, St. Jude Medical, St. Paul, MN) has become available for transcatheter closure of long patent ductus arteriosus (PDA) in infants.There are few case reports and one large series of the “off‐label” use of ADO II in non‐ductal positions . Because of its flexibility and low profile, it has been tried in retrograde approach instead of the previously used antegrade approach requiring the formation of an AV loop.…”

The hybrid perventricular closure of apical muscular ventricular septal defect with Amplatzer duct occluder

“…Since Amin's first report in 1998, the AMVSDO was introduced for muscular defects not only in congenital heart defects but also effectively in postmyocardial infarction VSD26-28). In relation with the particular VSD shape, an ADO has been the preferred choice by some authors29-31). MVSD is usually smaller in the RV side as compared to the LV, and often multiple in the RV side even in case with single in the LV side.…”

Oclusão percutânea de defeitos cardíacos congênitos e estruturais com amplatzer duct occluder II TM

“…Por causa de suas características vantajosas (flexibilidade, baixo perfil, segurança no implante e altas taxas de oclusão), a prótese ADO II passou a ser utilizada em outras cardiopatias congênitas e estruturais, como mostram a literatura [15][16][17][18][19][20] e este estudo. A opção pelo uso não-convencional de ADO II nesta casuística facilitou a abordagem dos defeitos, uma vez que um sistema de entrega de menor calibre pôde ser usado com maior facilidade para alcançar o posicionamento ideal de todo o conjunto, além de acarretar menor risco de lesão vascular.…”

“…A experiência inicial com esse dispositivo, tanto mundial como brasileira, é animadora. [8][9][10][11][12][13][14] Além disso, a prótese ADO II também tem sido utilizada para oclusão de outras lesões e defeitos intra e extracardíacos, incluindo anastomoses de Blalock-Taussig 15 , comunicações interventriculares perimembranosas 16 , musculares 16,17 ou residuais pós--cirúrgicas 18 , fistulas coronárias 19 e leaks paravalvares. 20 Neste estudo, descrevemos nossa experiência com o uso dessa nova prótese para o fechamento percutâneo de PCA e de outros defeitos congênitos e estruturais, discutindo suas vantagens, limitações, segurança e eficácia.…”
