Can you tell me more about cardiomyopathy and congenital heart disease?

Mixed: Cardiomyopathy means heart muscle disease. There are multiple causes. Some causes are abnormal proteins caused by a gene defect. Congenital heart disease conventionally refers to an abnormality that is present at birth in the structure of the heart or blood vessels in the chest. Severity and impact varies from trivial to fatal. Some congenital heart diseases can develop features of cardiomyopathy.
