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.

Dilated cardiomyopathy is a myocardial disorder in which there is systolic dysfunction and chamber dilation of one or both ventricles in the absence of a haemodynamic cause that can produce the existent dilation and dysfunction, including physiological (such as sepsis) or anatomic causes with either abnormal loading conditions (such as coarctation of the aorta) or ischaemia (such as coronary artery disease or anomalies).

Additional information: Physiological and anatomic conditions can affect the dilated cardiomyopathy morphofunctional phenotype. If this morphofunctional phenotype is retained after appropriate intervention, then a dilated cardiomyopathy is established.
