end-point and a post-mortem was performed. Virus in myocardial tissue was
confirmed using real time qPCR.
Results: All horses developed clinical signs of AHS. Signs included hypothermia;
tachycardia; tachypnoea; supraorbital fossa oedema; and petechial haemorrhages.
Infected horses showed severely impaired left ventricular systolic function
characterised by myocardial dyskinesis; decreased ejection fraction and fractional
shortening. cTnI was elevated in all cases.
Conclusions and significance: AHS is associated with severely impaired left
ventricular function. This implies an alternative cardiogenic mechanism for the
pulmonary oedema seen in clinical cases and provides a framework for therapeutic
intervention using cardiac specific drugs.

Introduction
Tendon and ligament injuries are one of the most common causes of wastage in
performance horses. Racehorses and other horses performing at the upper levels of
athletic competition have the highest incidence of these injuries. Ultrasonography
has enabled the practitioner to diagnose the presence of tendon and ligament injury,
characterize the type of injury and quantitate its severity. The relationship of the
ultrasonographic appearance of the tendons and ligaments to histopathologic
findings has provided additional documentation to the value of the ultrasonographic
examination of an injured tendon or ligament. Ultrasonography is also used to
assess tendon healing and is becoming an essential part of the rehabilitation
program for a horse recovering from a tendon or ligament injury.
Ultrasonographic Anatomy
Each tendon and ligament in the pastern region changes in size and shape from its
origin to its insertion. Therefore, knowledge of normal anatomy is critical to using
ultrasonography for the diagnosis of tendon or ligament injuries.
