Figure 28.1 Lateral and dorsoventral thoracic radiographs in three dogs with pericardial disease. (a,b) A 4‐month‐old English bulldog with
a peritoneopericardial diaphragmatic hernia seen as an abnormal gas pattern consistent with bowel loops within the cardiac silhouette.
(c,d) Severe enlargement of the cardiac silhouette with a large‐volume pericardial effusion in a dog that presented for cough. The trachea is
dorsally deviated. (e,f) The cardiac silhouette is enlarged with rounded borders in a dog with degenerative mitral valve disease. Left atrial
enlargement can be noted as straightening of the caudal aspect of the cardiac silhouette (arrows). The left atrium was severely enlarged on
echocardiography and a small‐volume pericardial effusion was documented that resolved with heart failure management.
