ABSTRACT
Middle aortic syndrome (MAS) is a rare vascular disease representing an important cause of severe hypertension in children. MAS is characterized by segmental or diffuse narrowing of the abdominal and/or distal descending aorta with involvement of the renal and visceral branches. Most cases of MAS are idiopathic, but MAS may occur in genetic and acquired disorders. The most common genetic causes of MAS are neurofibromatosis type I, Williams syndrome, Alagille syndrome, tuberous sclerosis and mucopolysaccharidosis. This review article discusses the pathophysiological aspects, distinctive associated features, and management of genetic forms of MAS in children.
ABSTRACT
Marfan syndrome (MFS) is an autosomal dominant inherited disease of the connective tissue with multiorgan involvement (skeleton, cardiovascular, eyes, skin, lungs). Cardiovascular involvement is variable and represents the major cause of morbidity and mortality in Marfan syndrome. We provide a comprehensive description of cardiovascular manifestations in Marfan syndrome, genotype-phenotype correlations and assessment of cardiovascular abnormalities and complications.
