Restrictive cardiomyopathy

Restrictive cardiomyopathy is the least common subtype of cardiomyopathy and is characterised by a marked decrease in ventricular compliance. 

Patients can present with symptoms and signs of left ventricular failure and/or right ventricular failure 9

It is predominantly a disease of diastolic dysfunction where the systolic (contractile) of the myocardium is usually unaffected. 

Recognised causes which can give a restrictive type pattern include:

The heart size can be normal. Sometimes there may be evidence of biatrial dilatation.

It shows diastolic dysfunction.

Cardiac MRI is useful for differentiating between constrictive pericarditis. Biatrial enlargement with minimal or no ventricular enlargement may be present. Cine MRI will show altered diastolic filling.
