Overview
Restrictive cardiomyopathy is defined as heart-muscle disease with impaired ventricular filling usually due to increased stiffness. The diastolic volume of either or both ventricles is normal or decreased,the systolic function usually remains normal and wall thickness may be normal or increased. The symptoms and signs may consist of right (jugular venous pressure, peripheral edema, and ascites) or left ventricular failure (breathlessness and evidence of pulmonary edema).[1]

Causes
Common Causes
- Idiopathic cardiomyopathy
- Amyloisosis
- Sarcoidosis
- Endomyocardial fibrosis
- Radiation
- Toxic effects of anthracycline
Complete Diagnostic Approach
A complete diagnostic approach should be carried out after a focused initial rapid evaluation is conducted and following initiation of any urgent intervention.
