A rare case of bioprosthetic pulmonary valve failure was caused by an allergic reaction to molybdenum. Allergy testing identified the metal, and treatment with immunosuppression and antihistamines improved valve function.
Area of Science:
- Cardiology
- Allergy and Immunology
- Biomaterials Science
Background:
- Bioprosthetic valve failure is a major complication in cardiac patients, often due to leaflet degeneration.
- Common causes include endocarditis, calcification, and thrombosis.
- Rare etiologies of valve failure require thorough investigation.
