Transcatheter Closure of Perimembranous Ventricular Septal Defects With Amplatzer Duct Occluders

We report the first case of transcatheter perimembranous ventricular septal defect (pmVSD) closure in Japan where none of existing devices for VSD closure has been approved. The pmVSD was successfully closed with first generation Amplatzer® duct occluder (ADO-I; St Jude Medical, St Paul, MN, USA). The procedure was performed under general anesthesia with transesophageal echocardiographic and fluoroscopic guidance. The left ventricular volume overload after the procedure was remarkably improved and no major complications occurred. ADO-I can be a safe and effective option for transcatheter pmVSD closure. The incidence of heart block may be less than reported with the original device.
