Osteogenesis imperfecta (OI), a collagen disorder, often involves heart valve issues. Surgical repair of mitral and aortic valves is possible but high-risk in OI patients.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Connective Tissue Disorders
Background:
- Osteogenesis imperfecta (OI) is a genetic disorder affecting collagen synthesis, leading to bone fragility.
- OI is associated with cardiovascular complications, including left-sided valvular regurgitation and aortic dilation.
- Cardiac surgery in OI patients presents significant risks due to the underlying connective tissue defect.
Purpose of the Study:
- To review valvular and aortic pathology in Osteogenesis imperfecta (OI).
- To discuss management strategies for cardiac conditions in OI patients.
- To report on surgical outcomes for valve repair and replacement in OI.
Main Methods:
- Literature review of valvular and aortic pathology in OI.
- Case report of two patients with OI experiencing significant aortic and mitral regurgitation.
- Detailed description of conservative management and surgical intervention (mitral valve repair and aortic valve replacement).
Main Results:
- Patients with OI can present with severe aortic and mitral valve regurgitation.
- Conservative management is one approach for cardiac issues in OI.
- Successful mitral valve repair and aortic valve replacement were performed in one OI patient, a rare procedure.
Conclusions:
- Valvular and aortic disease are recognized complications of Osteogenesis imperfecta.
- Surgical intervention for cardiac pathology in OI is feasible, though high-risk.
- Mitral valve repair in OI patients, while uncommon, can be successful, as evidenced by this case series.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
