In brief: Intrinsic/extrinsic

Restrictive cardiomyopathy involves the heart itself becoming stiff and not filling properly which eventually can cause heart failure and need a transplant to treat.
Constrictive pericarditis affects the sac around the heart entrapping the heart and causing similar symptoms but may be treated if needed by removing the sac from around the heart by surgery

In brief: Underlying cause

Clinically similar.Both restricts filling of the ventricles.
Although sometimes the echocardiogram and cardiac MRI will show findings favoring one over the other such as a thickened heart,thickened pericardium cardiac catheterization is often required. In restrictive cardiomyopathy the left ventricular pressure is higher than the right specially with fluid challenge.Similarly left atrial pressure

In brief: PERICARDITIS

Pericarditis is inflammation with fluid accumulation and reduced cardiac output.
Restrictive cardiomyopathy resist diastolic filling due to noncompliant ventricular walls.
