Type I aortic dissection in a patient with osteogenesis imperfecta

The previously undescribed association between aortic dissection and osteogenesis imperfecta is reported in a 39-year-old man with known osteogenesis imperfecta, who presented with a type I aortic dissection. His ascending aorta was repaired using a Dacron tube graft under hypothermic circulatory arrest but the patient died 12 h later, following re-dissection around the left coronary ostium resulting in massive myocardial infarction of the left ventricle.
