Two patients are described with mitral valve disease associated with osteogenesis imperfecta. The mitral valve showed the typical pathology associated with this condition -the prolapsed cusps and ruptured chordae. Both valves were operated on with cardiopulmonary bypass with the expected postoperative haemorrhagic problems. Both, however, left hospital satisfactorily.
Wood et al. (Mon,) studied this question.
