Osteogenesis imperfecta and Ebstein's anomaly: a case report with autopsy findings.

Osteogenesis imperfecta is an inherited disorder of collagen synthesis. It has a wide range of phenotypic expressions, but cardiovascular anomalies tend to be rare. When they do occur, they usually consist of aortic or mitral valve disease. We report an autopsy case of a 36-week gestation infant with coexisting osteogenesis imperfecta and Ebstein's anomaly. The simultaneous occurrence of two relatively rare entities may reflect a generalized expression of an underlying collagen synthesis defect.
