Radiographs are useful for the diagnosis of congestive heart failure, however they are not able to distinguish the underlying cardiomyopathy. Radiographs may reveal left atrial dilation. On the dorso-ventral projection, a classic 'Valentine heart' shape may be evident due to the marked left atrial/biatrial dilation.  Pulmonary venous conjestion, interstitial/alveolar pattern or the presence of a pleural effusion may be identified.  These findings are not specific for RCM.
