Percutaneous Closure of an Iatrogenic Inlet Ventricular Septal Defect in an Atrioventricular Canal

A 45-year-old woman with a partial atrioventricular canal presented with an iatrogenic interventricular shunt after implantation of a mechanical mitral prosthesis. The shunt was occluded percutaneously with an Amplatzer Duct Occluder II. This is the first reported percutaneous closure of a ventricular septal defect in an atrioventricular canal defect.
