Though there are various formal definitions of CMP in the literature, the two major ones are from the World Health Organization (WHO) and from the American Heart Association (AHA). The WHO definition is more clinical, while the AHA definition is more molecular and scientific in its delineation. For the purpose of this chapter, we follow the simpler definition by WHO as it lends itself well to the echocardiographic evaluation of cardiomyopathies.
