title: Iatrogenic embolization and transcatheter retrieval of a ventricular septal defect occluder in a dog.
abstract: A 7-month-old Irish Setter underwent transcatheter therapy of a muscular ventricular septal defect (VSD) and pulmonary valve stenosis. Standard devices for muscular VSD closure could not span the interventricular septum due to right ventricular hypertrophy, and an Amplatzer post-infarction muscular VSD occluder with a wider waist was successfully implanted. Following VSD closure, inflation of the balloon dilation catheter during balloon pulmonary valvuloplasty resulted in iatrogenic embolization of the VSD occluder to the left ventricular outflow tract. Retrieval and reimplantation of the device was achieved using a snare catheter. This report describes a potential complication and management during intracardiac device implantation in a dog. Additionally, the case illustrates that the Amplatzer post-infarction muscular VSD occluder holds potential value in animals with a hypertrophied interventricular septum that cannot be spanned using a conventional device.
