A four-year-old vasectomised Herdwick ram presented with a two-day history of inappetence, lethargy, weakness and exercise intolerance. Clinical examination revealed mild tachypnoea and hyperpnoea and marked tachycardia and pallor. No anaemia was present. Thoracic ultrasonography revealed thickening of the right ventricular wall and increased pericardial and peritoneal fluid. A diagnosis of congestive heart failure was made and the animal was euthanased. Necropsy revealed a subendocardial abscess adjacent to the right atrioventricular valve, the leaflets of which were distorted. The gross appearance of this lesion is similar to that described for valvular ring abscesses in human beings.
