Apical Hypertrophic Cardiomyopathy in an Infant: First Presentation of Pompe's Disease.

Pompe's disease is a type II glycogen storage disorder resulting from deficiency of α-1,4 glucosidase. It is usually associated with dilated or hypertrophic cardiomyopathy. Association of apical hypertrophic cardiomyopathy is rarely seen. We present a case of a ten-month-old baby with clinical features of both apical hypertrophic cardiomyopathy and Pompe's disease.
