Insights

Intracardiac prosthetic materials can cause hemolytic anemia. A muscular ventricular septal defect occluder led to severe anemia, necessitating its removal and repair.

Area of Science:

  • Cardiology
  • Hematology
  • Biomaterials Science

Background:

  • Intracardiac prosthetic materials are associated with hemolytic anemia.
  • Hypertrophic obstructive cardiomyopathy is a condition affecting heart muscle.
  • Ventricular septal defects (VSDs) are holes between the heart's ventricles.

Observation:

  • A 74-year-old female with hypertrophic obstructive cardiomyopathy underwent closure of a postoperative ventricular septal defect.
  • A muscular ventricular septal defect occluder was used for closure.
  • The patient developed intractable hemolytic anemia following the procedure.

Findings:

  • The muscular ventricular septal defect occluder was identified as the cause of the severe hemolytic anemia.
  • Surgical removal and repair of the occluder were required to resolve the anemia.
  • This case highlights a rare complication of transcatheter VSD closure.

Implications:

  • This case underscores the potential for intracardiac devices to cause hemolysis.
  • Careful patient selection and device choice are crucial for VSD closure.
  • Further research into biomaterial interactions with blood is warranted.
