Valvular heart disease in patients with osteogenesis imperfecta.

Osteogenesis imperfecta (OI) or "brittle bone disease" is a rare connective tissue hereditary disorder. The most common clinical presentation of OI is bone fractures. OI also involves extraskeletal structures; however, cardiovascular manifestations are rare. In this report, we describe the cardiovascular anomalies of patients with OI who underwent valve surgery and review the literature on this subject.
