Plain-English summary

A 5-month-old male foal was experiencing repeated fevers and had a noticeable heart murmur, which later led to signs of heart failure. Tests on his blood and fluid from his abdomen showed a very high number of white blood cells, indicating an infection or inflammation. Unfortunately, after he passed away, a thorough examination revealed that he had both a serious heart defect called Tetralogy of Fallot and inflammation of the cranial mesenteric artery. The findings from both the clinical observations and the examination after death provide important insights into this case.

Abstract

A 5 month old colt foal with recurrent pyrexia and a loud pansystolic murmur later developed signs of cardiac failure. Peritoneal fluid and blood samples both demonstrated an extreme leucocytosis and neutrophilia. At post-mortem both a cranial mesenteric arteritis and the congenital cardiac anomaly, Tetralogy of Fallot were found. The detailed clinical and post-mortem findings contributing to the case are described.
