===Echocardiography===
===Echocardiography===
This is the diagnostic test of choice for identification of RCM and excluding other cardiomyopathies.
Two-dimensional (2D) and M-mode imaging may reveal pronounced dilation of one or both atria and normal diameter and thickness of the ventricular chambers. Within the left atrium it is often possible to identify areas of spontaneous echo-contrast, reflecting blood stasis, or thrombi.
===Endomyocardial form of Restrictive Cardiomyopathy (eRCM)===
This form of RCM is characterised by severe endomyocardial fibrosis with a 'bridging scar' crossing the left ventricle. This endomyocardial bridging scar may be associated with left ventricular obstruction during systole. In early forms, focal left ventricular hypertrophy may be evident, which over time progresses to the formation of a 'bridging scar'.
===Myocardial form of Restrictive Cardiomyopathy (mRCM)===
In this form of RCM, the left ventricle appears normal, but there is concurrent left atrial or biatrial enlargement.
