Marfan syndrome is a hereditary disease that presents ocular, skeletal, and cardiovascular abnormalities. In recent years, there have been several reports of patients with familial cardiovascular disease but no physical features of Marfan syndrome. We encountered 3 cases of familial annulo-aortic ectasia (AAE). Their father had also had aortic regurgitation, and died during surgery 10 years before. No case demonstrated any physical characteristics of Marfan syndrome or any other connective tissue disease. All cases were operated successfully. One case showed cystic medial necrosis, and 2 cases showed degenerative change. The present report suggests that familial AAE may be caused by weakness of the aortic wall related to heredity. If AAE is left untreated, it can lead to aortic dissection. Thus, we recommend that patients with familial AAE should undergo screening and follow-up similar to patients with Marfan syndrome.
