ICD-11

These are myocardial disorders in which the heart muscle is structurally and functionally abnormal, in the absence of coronary artery disease, hypertension, valvular disease and congenital heart disease sufficient to cause the observed myocardial abnormality.

Restrictive cardiomyopathy is the presence of impaired ventricular diastolic function related to reduced rate and/or extent of relaxation and/or compliance in the absence of another predominant phenotype of dilated or hypertrophic cardiomyopathy.

Nonfamilial restrictive cardiomyopathy is restrictive cardiomyopathy secondary to an acquired systemic disorder that is known to be associated with restrictive cardiomyopathy such as amyloidosis, scleroderma, sarcoidosis, or anthracycline therapy.
