Towards a New Classification of Cardiomyopathies.

The paper uses the recently advocated concept of arrhythmogenic cardiomyopathy as an example of the limitations of current classification systems. At present, there is no single classification system that meets the needs of all potential users, whether they are basic scientists, clinicians, patients or families. The classical cardiomyopathy subtypes still have utility, but future disease notation needs to be modified to take into account the new and more complete phenotypes and aetiologies.
