UNLABELLED: Severely affected children with congenital disorder of glycosylation type Ia (CDG-Ia; MIM 212065) may develop hypertrophic cardiomyopathy. In this report we describe the near-death of a 10-month-old girl with CDG-Ia due to acute left-ventricular outlet obstruction caused by hypertrophic cardiomyopathy and acute dehydration. The girl had multi-organ failure and signs of severe myocardial damage mimicking myocardial infarction. CONCLUSION: hypertrophic cardiomyopathy contributes to the high mortality of young children with congenital disorder of glycosylation type Ia. Even if cardiomyopathy in this disease is non-obstructive, acute fluid-loss might cause left ventricular outflow tract obstruction and life-threatening myocardial ischaemia. Patients with congenital disorder of glycosylation type Ia are at risk for cardiac complications and should be monitored regularly by echocardiography.
