Mitochondria are the major site of energy production in the cell. It is not surprising, therefore, that an energy dependant tissue such as heart is affected by mitochondrial dysfunction. In this issue, Holmgren and colleagues1 report the cardiological findings and clinical course of 17 children with cardiomyopathy identified from a large cohort of children with mitochondrial disease. This is an important study that provides essential information concerning the cardiological features of what are becoming increasingly common disorders. Moreover, it is one of the first studies to provide some information about the natural history of cardiac disease in this group.
Mitochondrial disease in the context of this study means disease arising from defects of the mitochondrial respiratory chain (MRC). The MRC consists of five multi-subunit complexes embedded in the inner mitochondrial membrane. Its function is to conserve the energy released by the oxidativemetabolism
