Definition : A form of cardiac muscle disease in which the ventricular walls are excessively rigid,
impeding ventricular filling. It is marked by reduced diastolic volume of either or
both ventricles but normal or nearly normal systolic function. It may be idiopathic
or associated with other diseases (endomyocardial fibrosis or amyloidosis) causing
interstitial fibrosis. [MeSH];
