Dilated Cardiomyopathy
Dilated
cardiomyopathy is the most common type of
cardiomyopathy, and also called congestive cardiomyopathy. In DCM, the
heart is enlarged in size and its walls tend to be thin (thus the term
dilated). 
The
image below shows marked dilatation of the ventricles compared to the size
of the atria.
