title: Left atrial rupture in osteogenesis imperfecta.
abstract: A 60 year old man with features of osteogenesis imperfecta presented in biventricular failure with evidence of mitral regurgitation. He responded to conventional treatment but later collapsed and died at home. Necropsy showed a haemopericardium caused by a tear in the left atrium. There was also rupture of the mitral chordae tendineae.
