Marfan syndrome is a systemic disease of connective tissue characterized by a variable combination of cardiovascular (dilation of the aorta , mitral insufficiency), musculo-skeletal (excessive length of extremities, scoliosis...), ophthalmic (myopia...) and pulmonary manifestations(pneumothorax...). With regular follow-up and adequate management, patients now have a life expectancy close to that of the general population.
