A case of hemolysis after percutaneous ventricular septal defect closure with a device.

Hemolytic anemia related to intracardiac prosthetic materials has been described. We describe a case of a 74-year-old female with a history of hypertrophic obstructive cardiomyopathy that had a postoperative ventricular septal defect closed with a muscular ventricular septal defect occluder. The device caused intractable hemolytic anemia that required surgical removal and repair. We describe a rare cause of hemolysis complicating transcatheter closure of a post-traumatic ventricular septal defect.
