    Cardiac abnormalities are common in osteogenesis imperfecta (OI). Echocardiography revealed aortic root dilation and valve issues in many of the 20 OI patients studied, highlighting the need for cardiac monitoring.

    Area of Science:

    • Cardiology
    • Genetics
    • Pediatrics

    Background:

    • Osteogenesis imperfecta (OI) is a rare genetic disorder characterized by brittle bones.
    • Cardiac involvement in OI is not well-documented, necessitating further investigation.
    • Previous studies suggest a potential link between OI and cardiovascular abnormalities.

    Purpose of the Study:

    • To determine the prevalence of cardiac abnormalities in patients with osteogenesis imperfecta.
    • To characterize the specific types of cardiac findings in this population.
    • To correlate cardiac findings with clinical presentation and severity of OI.

    Main Methods:

    • A clinical and echocardiographic study was conducted on 20 patients diagnosed with osteogenesis imperfecta.
    • Echocardiography was used to assess cardiac structure and function, including aortic root diameter, valve morphology, and presence of murmurs.

  • Patients were evaluated for systemic hypertension and other relevant clinical parameters.

    • Main Results:

    • Aortic regurgitation was present in one patient.
    • Thirteen patients exhibited soft late apical systolic murmurs, without significant mitral regurgitation.
    • Seven patients had systemic hypertension, and six showed aortic root diameter exceeding normal ranges.
    • Echocardiographic findings suggested thin left-sided valve cusps in some patients, with coarse systolic flutter of aortic valve leaflets observed in 13 patients.

    Conclusions:

    • Cardiac abnormalities, including aortic root dilation and valve abnormalities, are prevalent in patients with osteogenesis imperfecta.
    • Systolic murmurs and aortic valve leaflet flutter are common echocardiographic findings in OI patients.
    • Regular cardiac screening is recommended for individuals with OI to detect and manage potential cardiovascular complications early.
