Severe Hemolysis after Implantation of a Rashkind Occluder in a Large Ductus

We report an unusual case of severe mechanical hemolysis after implantation of a 17-mm Rashkind patent ductus arteriosus occluder in a young adult female with a large ductus. The device failed with conservative management, including implantation of a second occluder, and surgery was required to close the ductus. This occluder may not be suitable for closure of a large patent ductus arteriosus.
