Mucopolysaccharide storage disease (MPS) presents clinically with a broad spectrum of abnormalities, among which cardiovascular involvement has been described. The echocardiographic findings have recently been reported for the various types of MPS. Among these, asymmetric septal hypertrophy (ASH) has been documented. We present a case of a 9-year-old girl suffering from type I MPS, atypical variant, with echocardiographic signs of ASH. She was given a bone marrow transplant after which the hypertrophic cardiomyopathy regressed.
