    Summary
    This summary is machine-generated.

    Idiopathic arterial calcification in infancy (IACI) is a rare, fatal condition causing cardiac failure in infants. This study reports three cases, highlighting myocardial ischemia and pulmonary hypertension as primary causes of death.

    Area of Science:

    • Cardiovascular Pathology
    • Pediatric Cardiology
    • Genetics

    Background:

    • Idiopathic arterial calcification in infancy (IACI) is a rare, severe genetic disorder.
    • It leads to widespread arterial calcification and stenosis, primarily affecting the internal elastic lamina.
    • Early diagnosis and understanding of IACI are crucial for managing affected infants.

    Observation:

    • Three fatal cases of IACI in infants aged 9 days to 3 months are presented.
    • Clinical presentation included severe cardiac dysfunction.
    • Histological examination revealed extensive arterial calcification.

    Findings:

    • Two infants died from myocardial ischemia secondary to coronary artery calcification.
    • One infant succumbed to pulmonary hypertension due to calcification of pulmonary arteries.

  • Autopsy findings confirmed widespread arterial calcification affecting major vessels.

    • Implications:

    • This case series underscores the critical role of cardiac failure in IACI mortality.
    • Understanding the specific mechanisms of cardiac compromise (ischemia vs. hypertension) is vital for prognosis.
    • Further research into the genetic basis and potential therapeutic targets for IACI is warranted.
