Pediatric restricted cardiomyopathy

Restrictive cardiomyopathy (RCM), also known as occlusive cardiomyopathy, is relatively rare. Endocardial and / or myocardial disease reduces ventricular dilatation, impairs diastolic filling, and causes heart failure. Restrictive cardiomyopathy is endocardial and subendocardial myocardial fibrosis and hyperplasia, mural thrombosis, contraction or occlusion of the heart cavity, impaired ventricular filling and decreased compliance, severely impaired diastolic function, and contractile function remains normal or Mild damage is characterized by cardiomyopathy.
