Severe ventricular dysfunction can also be the result of coronary artery disease with subsequent loss of viable myocardium. These conditions are what define specific cardiomyopathies, however, there are several intrinsic disorders of the myocardium itself that can lead to different types of cardiomyopathies.

This book highlights some of the unique types of cardiomyopathies.
