Mitral stenosis in the Maroteaux-Lamy syndrome: a treatable cause of dyspnoea.
نویسندگان
چکیده
The case is reported of a young woman with the Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI) who presented with rapidly progressive dyspnoea due to mitral stenosis. Mitral valve replacement was performed and the appearance of the valve was typical of mucopolysaccharide infiltration. Dyspnoea in patients with the Maroteaux-Lamy syndrome may be due primarily to cardiac valve involvement, and in this setting, valve surgery is safe and effective.

Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI) is a rare lysosomal storage disorder in which the pathologic storage of glycosaminoglycans in various tissues can lead to severe symptoms, including cardiomyopathy. We report on a child with Maroteaux-Lamy syndrome whose cardiac condition deteriorated and eventually led to cardiac failure at the age of 7 years due to severe mitral regurgit...

Mucopolysaccharidoses (MPSs) are a group of metabolic diseases transmitted in an autosomal recessive fashion. MPSs are due to deficiencies of the specific enzymes responsible for the catabolism of dermatan sulfate, heparin sulfate, and keratan sulfate, resulting in the accumulation of glycosaminoglycans (GAGs). MPSs have a chronic, progressive course with multisystemic involvement. The incidenc...

Mucopolysaccharidosis type maroteaux-lamy is a very rare hereditary disease. The disease is marked by the deficiency of the lysosomal enzyme N-Acetyl galactosamine-a-4-sulfate sulfatase (arylsulfatase B). It is inherited as an autosomal recessive trait. The most clinical manifestations are: corneal clouding, organomegaly, hernias, coarse facial features, cardiac insufficiency and skeletal abn...
