This heart condition is a common cause of severe abdominal pain in cattle, predominantly dairy cattle. It is very rare in other animals. It is caused by ingestion of wire or other piece of metal into the rumen of the cow. Ruminal movements can cause the wire to penetrate the cranial reticulum and therefore penetrate the pericardium and/or liver causing pericarditis.

Clinical Signs

The animal will usually appear dull and depressed and may stand away from the herd. She will often show extension of the neck, arching of the back and stand with elbows abducted, which are all signs of cranial abdominal discomfort. There will often also be signs of right sided heart failure and peripheral oedema.

Diagnosis

History and clinical signs may be indicative of the disease. On physical exam, the cow will elicit a grunt (pain response) when pressure is applied to the ventral abdomen. She will often be pyrexic, have increased pulses and decreased rumen sounds. The faeces may be dry and mucus covered and there will be a noticeable tachycardia. On auscultation of the heart, one may hear 'whooshing' sounds over the heart noises, indicating presence of fluid in the pericardium.

Blood tests may show a neutrophilia with a left shift, increased fibrinogen and increased serum total protein.

Fluid analysis of fluid from the pericardium will confirm traumatic pericarditis, by showing presence of bacteria within neutrophils as well as a large number of degenerate neutrophils.

Treatment

Confine the animal to prevent stress from the rest of the herd. Administer broad spectrum antibiotics immediately. A rumenotomy should be performed and a hand guided down into the cranial rumen or reticulum to find and remove the foreign object. However, although these treatment options are all viable, the animal is usually culled on economic grounds in most cases.

Prevention through good husbandry practices, such as a magnet in the feeding wagon etc, is the best control measure.
