Heart involvement in hepatolenticular degeneration

Area of Science:

• Cardiology
• Genetics
• Histopathology

Background:

• Hepatolenticular degeneration (Wilson disease) is a genetic disorder of copper metabolism.
• Cardiac involvement in Wilson disease is often underdiagnosed, presenting with varied clinical manifestations.

Observation:

• A 10-year-old boy with a mild abdominal form of hepatolenticular degeneration presented with clinical, laboratory, and histological signs of cardiac involvement.
• Myocardial biopsy revealed moderate myocardial damage and significant copper deposition, nearly 10 times the normal concentration.

Findings:

• Histochemical analysis using rubeanic acid confirmed copper deposition in myocardial tissue.
• The study establishes a correlation between the degree of copper storage and the observed myocardial damage.

Implications:

• Early cardiac evaluation is crucial for patients with hepatolenticular degeneration.
• Understanding copper deposition patterns can improve diagnosis and management of cardiac complications in Wilson disease.
