Surgical treatment for mitral stenosis in Scheie's syndrome: mucopolysaccharidosis type I-S.

Scheie's syndrome is a subtype of mucopolysaccharidosis, which is a rare hereditary disorder of proteoglycan degrading enzymes. Deposition of mucopolysaccharide often causes cardiac disease, especially valvular lesion, but reports of its surgical treatment have been rare. We report a case of 41-year-old woman with Scheie's syndrome who successfully underwent mitral valve replacement for mitral stenosis.
