Summary

Mucopolysaccharidoses (MPS) cause heart valve problems like mitral valve thickening in most patients. Early cardiac screening is vital for all individuals with MPS to detect and manage these cardiovascular issues.

Area of Science:

  • Cardiology
  • Genetics
  • Metabolic Disorders

Background:

  • Mucopolysaccharidoses (MPS) are inherited lysosomal storage diseases.
  • Impaired glycosaminoglycan degradation is the hallmark of MPS.
  • Cardiac involvement is common in MPS but its clinical significance requires further study.

Purpose of the Study:

  • To evaluate the prevalence and types of cardiovascular abnormalities in patients with MPS.
  • To identify specific cardiac lesions associated with different MPS types.
  • To determine the clinical impact of cardiac involvement in MPS patients.

Main Methods:

  • Cross-sectional study involving 39 patients diagnosed with MPS.
  • Patients' ages ranged from 4 to 22 years.
  • Comprehensive cardiological investigations were performed.

Main Results:

  • Valvular lesions were detected in a significant portion of the MPS patient cohort.
  • Mitral valve thickening, with or without regurgitation or stenosis, was the most frequent finding.
  • Severe cardiac changes were most pronounced in Mucopolysaccharidoses types I and II.

Conclusions:

  • Cardiac abnormalities, particularly valvular lesions, are highly prevalent in patients with MPS.
  • Routine cardiological assessment is recommended for all individuals diagnosed with MPS.
  • Early detection and management of cardiac complications are crucial for improving outcomes in MPS patients.
