Cardiovascular involvement is relatively rare in osteogenesis imperfecta and has a predilection for left-sided cardiac valves. We report a 5 years old female child affected by osteogenesis imperfecta type I in which an asymptomatic mild form of Ebstein's anomaly, a congenital tricuspid malformation, was diagnosed during routinely investigation. The association of these two relatively rare entities could provide new insight to better understand the pathogenesis of cardiac involvement in osteogenesis imperfecta.
