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.

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 in cases of left-sided congestive heart failure. Dilation of the caudal vena cava may be observed if right-sided congestive heart failure is present. These findings are not specific for RCM.
