Left atrial rupture in osteogenesis imperfecta

Area of Science:

• Cardiology
• Genetics
• Pathology

Background:

• Osteogenesis imperfecta (OI) is a group of genetic disorders characterized by fragile bones.
• Cardiac manifestations, though less common, can occur in OI patients.
• Biventricular failure and mitral regurgitation are significant cardiac complications.

Observation:

• A 60-year-old male with features of osteogenesis imperfecta presented with biventricular failure and mitral regurgitation.
• Initial response to conventional treatment was observed.
• The patient subsequently collapsed and died at home.

Findings:

• Necropsy revealed a fatal hemopericardium.
• The hemopericardium was attributed to a tear in the left atrium.
• Rupture of the mitral chordae tendineae was also identified.

Implications:

• This case underscores the potential for severe, life-threatening cardiac events in individuals with osteogenesis imperfecta.
• Early recognition and management of cardiac complications in OI are crucial.
• Further research into the cardiovascular pathology of OI is warranted.
