SAEVA Congress 2018 Proceedings | 12-15 February 2018 | ATKV Goudini Spa 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.

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. 180
